with non-associated products or non-associated documentation can lead to incorrect interpretation and thus result in injury and damage.

Operating conditions, positions and locations The product should only be operated in the operating conditions, positions and locations specified by the manufacturer such that ventilation is not obstructed. Non-observance of the manufacturer specifications can result in electric shock, fire and/or serious or (under certain circumstances) fatal injury. All work must be performed in compliance with the local or country-specific safety and accident prevention regulations. 1. Unless otherwise agreed, the following points apply for Rohde & Schwarz products: a) b) c) d) e) f) g) h) i)

Operating position: housing base at bottom IP degree of protection: 2X Degree of soiling: 2 Overvoltage category: 2 For indoor use only Operation up to 2000 m above sea level Transport up to 4500 m above sea level Tolerance for nominal voltage: ± 10 % Tolerance for nominal frequency: ± 5 %

2. Do not stand the product on surfaces, vehicles, shelves or tables that are not suitable for weight or stability reasons. When mounting and securing the product on/to objects or structures (e.g. walls and shelves), always follow the installation instructions from the manufacturer. Persons can be injured or even killed if installation is not performed in the way described in the product documentation. 3. Do not place the product on appliances that generate heat (e.g. radiators and fan heaters). The ambient temperature must not exceed the maximum temperature specified in the product documentation or in the data sheet. Overheating of the product can result in electric shock, fire and/or serious or (under certain circumstances) fatal injury. Electrical safety Non-observance or inadequate observance of the instructions concerning electrical safety can result in electric shock, fire and/or serious or (under certain circumstances) fatal injury. 1. Before switching on the product, always make sure that the nominal voltage set at the product matches the nominal AC voltage of power supply network.

Safety Instructions

R&S THU9/TMU9


3. Any deliberate interruption of the PE conductor (both along the feed line and at the product itself) is not permitted. This can result in a potential shock hazard at the product. If extension cables or multipoint connectors are used, it must be ensured that their safety is checked at regular intervals. 4. If the product is not equipped with a power switch to disconnect it from the power supply, the plug on the connecting cable must be used to disconnect the power supply. In such cases, it must be ensured that the power plug is easily reachable and accessible at all times (length of connecting cable approx. 2 m). Function switches or electronic switches are not suitable for disconnecting the product from the power supply. If products without power switch are integrated in racks or systems, the disconnecting device must be provided at system level. 5. Never use the product if the power cable is damaged. Check at regular intervals that the power cable is in perfect condition. Take suitable precautions and use suitable cable installation methods to ensure that the power cable cannot be damaged and personnel cannot be injured (e.g. as a result of electric shock or tripping over cables). 6. Operation is only permitted in TN/TT supply networks which are fuse-protected with max. 16 A (higher fuse ratings should only be used after consultation with the Rohde & Schwarz company group). 7. Do not insert the plug into dusty or dirty sockets. Insert the plug firmly and completely into the sockets provided. Disregard of these points can lead to sparks, fire and/or injury. 8. Do not overload the sockets, extension cables or multipoint connectors as this can cause fire or electric shocks. 9. In the case of measurements in electrical circuits with voltages Urms > 30 V, appropriate measures must be taken to avoid all hazards (e.g. suitable measuring equipment, fuse protection, current limiting, electrical separation, insulation, etc.). 10. In the case of connections to IT equipment (e.g. PCs or industrial computers), it must be ensured that such connections satisfy the applicable IEC60950 ‑1/EN60950 ‑1 or IEC61010 ‑1/EN61010 ‑1. 11. Unless explicitly permitted, never remove the cover or any part of the housing while the product is in operation. Electrical lines and components will otherwise be exposed, which can lead to injury, fire or damage to the product. 12. If the product is connected at a fixed location, the connection between the on‑site PE conductor connection and the instrument PE conductor must be set up before any other connections are made. Installation and connection should only be performed by an electrician. 13. In the case of permanently installed equipment without built‑in fuses, circuit breakers or similar protective devices, the supply circuit must be fused in such a way that personnel who have access to the product, as well as the product itself, are adequately protected.

14. Every product must be protected against overvoltage (e.g. as a result of a lightning strike) by means of appropriate overvoltage protection. The operating personnel are otherwise at risk of electric shock. 15. Foreign objects must not be inserted into the openings of the housing. This can cause short circuits in the product and/or electric shocks, fire or injury. 16. Unless otherwise specified, products are not protected against the penetration of fluids; see also the section "Operating conditions, positions and locations", point 1. The instruments must therefore be protected against the penetration of fluids. If this point is disregarded, there is a risk of electric shock for the user or of damage to the product, which in turn can also endanger personnel. 17. Do not use the product under conditions in which condensation could occur (or may already have occurred) in or on the product, e.g. if the product has been moved from a cold environment into a warm environment. Water penetration increases the risk of electric shock. 18. Before cleaning the product, fully disconnect it from the power supply (e.g. power supply network or battery). Clean instruments using a soft, lint-free dust cloth. Never use chemical cleaning agents such as alcohol, acetone or cellulose thinner. Operation 1. Use of the product requires special instruction and full concentration during use. It must be ensured that persons who operate the product are fit to do so from a physical, intellectual and mental viewpoint, otherwise there is a risk of injury or damage. It is the responsibility of the employer/operator to select suitable personnel to use the product. 2. Before moving or transporting the product, read and observe the information in the section "Transport" on page 16. 3. As with all industrially manufactured goods, it is not possible to completely rule out the use of materials which cause allergies, i.e. "allergens" (e.g. nickel). If, when using Rohde & Schwarz products, allergic reactions occur (e.g. skin rash, frequent sneezing, red eyes or respiratory problems), consult a doctor immediately in order to determine the cause and to prevent health problems. 4. Before mechanically and/or thermally processing or dismantling the product, it is essential to refer to the section "Disposal" on page 16, point 1. 5. Owing to the inherent functional design of certain products (e.g. RF radio systems), increased electromagnetic radiation may be produced. In order to protect unborn life, pregnant women must be protected by means of suitable measures. Electromagnetic radiation also poses a risk to persons with pacemakers. The employer/operator is obliged to assess and identify workplaces where there is a particular risk of exposure to radiation, and to take precautions to prevent potential hazards.

6. In the event of fire, toxic substances (gases, fluids, etc.) can be discharged from the product and damage the health of personnel. If a fire occurs, appropriate measures must therefore be taken (e.g. breathing masks and protective clothing). 7. If a laser product is integrated in an Rohde & Schwarz product (e.g. CD/DVD drive), no settings or functions other than those described in the product documentation should be used in order to prevent injury (e.g. from the laser beam). Repair and servicing 1. The product should be opened by authorized specialist personnel only. Before any work is performed on the product or before the product is opened, it must be disconnected from the supply voltage, otherwise there is a risk of electric shock. 2. Any adjustments, part replacements, maintenance or repairs should be carried out only by authorized Rohde & Schwarz electricians. If safety‑relevant parts (e.g. power switches, power transformers or fuses) are to be changed, they must always be replaced with original parts.

Special Hazard Information

2.3 Special Hazard Information

2.3.1

Hazards from AC Supply Voltage All voltages of Urms > 30 V AC or U > 60 V DC must be regarded as constituting a shock hazard. When working with voltages that constitute a shock hazard, appropriate measures must be taken to prevent exposure to danger. Never work on live components. Work on live parts should only be performed in exceptional cases and only if special safety precautions are taken.

2.3.1.1

2.3.1.2

2.3.2

AC Power Supply ●

Before connecting the AC power supply, it is important to ensure that the power supply specifications given for the system or instruments match the nominal specifications for the local power supply network. The power supply circuit must be protected by means of fuses in order to prevent overloads and short circuits.

●

Miniature modules have neutral conductor fuses. As a result, the power supply may still be connected even after interruption of the circuit by a fuse.

Changing Fuses ●

Fuses which are accessible to the operator should only be changed after the instruments have been disconnected from the power supply. They must always be replaced with fuses that have the same electrical rating, tripping characteristics and breaking capacity.

●

Motor protection switches and automatic line fuses in those parts of a transmitter system that can be accessed by users must be tripped. If their response range is adjustable, the ex‑factory setting must not be altered. If settings are changed inadvertently, the correct values specified in this documentation must be set.

Hazards from High Energy Electric Circuits The instruments contain low-voltage circuits that can be fed from a voltage source with an extremely low impedance (e.g. amplifier operating voltage). These circuits carry dangerously high levels of energy. At Rohde & Schwarz, we treat these circuits in the same way as circuits with hazardous contact voltages. Normally, these circuits are protected by covers to prevent unintentional contact. The cover has a warning label. In practice it has been repeatedly shown that short circuits caused by small metallic tools result in severe burns. For safety reasons, any high‑energy electric circuits in areas of the equipment that can be accessed by users are concealed by protective covers. ●

Exercise the same amount of caution for measurements on low‑impedance voltages (e.g. for repair purposes) that you would when performing measurements on operating voltages which constitute a shock hazard. Wear suitable protective gear when necessary.

R&S THU9/TMU9


●

Before opening any equipment or removing a particular cover, turn off the power supply and wait 5 minutes to ensure that capacitors have discharged sufficiently.

●

Do not discharge capacitors by short‑circuiting them.

2.3.3

Hazards from RF Radiation

2.3.3.1

Obligation to Instruct Personnel ●

The operator must train all personnel in the operation of this transmitter or instrument in line with EN60215 and/or IEC215. It is essential that these regular training sessions emphasize the dangers related to high frequency that exist at the respective transmitter or instrument. Operating personnel are only authorized to adjust and operate the equipment after they have completed the respective training sessions and their participation has been documented.

High‑energy RF circuits inside the transmitter or instrument are routed via conventional removable RF connectors (e.g. type N). Depending on the output power, the output ports of the transmitter and instrument are equipped with screw-type or plug-in RF lines or ducts. If RF lines or modules carry high power, the connection point or the entire module is tagged with the general danger warning label (yellow triangle with a black exclamation mark).

2.3.3.2

RF Shielding Transmitters and instruments from Rohde & Schwarz are shielded so that even in the immediate vicinity there is no danger from RF radiation when all RF lines are connected. This applies to statutory provisions in Germany, i.e. the regulation concerning electromagnetic fields: Limits for electrical and magnetic field strengths of high ‑frequency installations are defined in the 26th ordinance of the German Federal Government's Emission Control Act of December 16, 1996 (26. BImSchV).

2.3.3.3

Rules When Operating an Amplifier Disconnecting RF lines that are in operation can result in arcs. These can cause burns and eye injuries. ●

Operation of the amplifier is only permitted if a main or dummy antenna is connected

●

Never disconnect RF lines when the amplifier is in operation

●

Never open the amplifier or modules when the amplifier is in operation

●

Never operate the amplifier if RF lines are exposed

2.3.3.4

Rules When Working on an Open Amplifier Operation with RF power is not permitted if the instrument has been opened or covers have been removed.

2.3.4

Conditions for Assembly Work on Cooling System The operator has to ensure that all installation, inspection and assembly work is performed by authorized and qualified personnel who have read and understood the operating instructions. Work on the system may be performed only with the system at rest and de‑energized, i.e. with all electric power supplies disconnected and switched off. All operating and safety instructions must be observed when working on the cooling system. Non‑observance of the safety instructions can result in injury to personnel, damage to the equipment and forfeiture of all claims for damages. Applicable accident prevention regulations must be observed. Precautions to prevent hazards resulting from electrical energy must be taken. Relevant VDE and IEC/IEEE regulations as well as the regulations of local power companies must be observed. When performing installation and assembly work, use only the original parts supplied. Any modifications to the system require the prior agreement of the manufacturer. To ensure the safety of the system, it is important to use only original spare parts and accessories approved by the manufacturer. If parts other than the original ones are used or alterations are made to the system, all claims for damages against the manufacturer shall be forfeited. In such cases, the manufacturer shall not be liable for any consequential or indirect damage. Safe and reliable operation of the system can only be ensured if the system is used for the intended purpose and the operating instructions are observed. Limit values specified in the operating manual must never be exceeded. Elements or subassemblies of the pump unit may be heated by the coolant, especially after extended periods of use under unfavorable conditions. Depending on the coolant return temperature, direct contact with the elements and subassemblies of the pump unit (pipes, tubes, reservoirs, etc.) should therefore be avoided wherever possible. For safety reasons, the coolant should be allowed to cool down to between 5 °C and 30 °C before the system is drained. Inappropriate handling of the coolant may be harmful to your health. For this reason, wear waterproof gloves and safety goggles during all maintenance and service work involving direct contact with the coolant. If your eyes or skin have come into contact with coolant, use tap water to wash it out immediately and thoroughly. Consult a doctor if necessary. If you have swallowed coolant, consult a doctor immediately in all cases. The coolant may contain an antifreezing agent which contains glycol.

4.1.1.4

N+1 Redundancy The task of the N+1 automatic function is to provide a B standby transmitter for up to eight A transmitters. This B transmitter takes over the program of an A transmitter if an A transmitter signals a fault. The output of the B transmitter is normally connected to a dummy antenna. The B transmitter is connected to an antenna by the N+1 automatic function as soon as the B transmitter takes over the program of the A transmitter. Manual Switchover Manual switchover of a program from an A transmitter to the B transmitter is performed by connecting the A transmitter concerned to the dummy antenna (button: To Load on the corresponding A transmitter). As a result of this switchover, a) the A transmitter becomes the standby transmitter for the B transmitter and b) the B transmitter is now no longer available as the standby transmitter for other A transmitters (exception: priority control). Automatic Switchover If the N+1 automatic function is active and ready for operation and the A transmitter is available for the N+1 automatic function, a fault in the A transmitter causes the program to switch over to the B transmitter. The N+1 automatic function signals the switchover by changing its status to "changed". The user can now either acknowledge the switchover by pressing the "Accept changeover" key and adopt it as the new operating state, or attempt by pressing the "Reset Faults" key to reset the N+1 automatic function to the original state and to delete the fault which caused the switchover. Configuring N+1 Automatic Function The switching behavior of the N+1 automatic function with regard to checkout times and automatic switchback can be configured according to individual requirements. Furthermore, for the B transmitter it is possible to define the A transmitter from which the program settings are to be adopted when the B transmitter operates as a standby transmitter. Configuring Program Specific Settings The B transmitter must store all program‑specific settings of all A transmitters internally so that they can be activated immediately in the event of a fault. Program‑specific settings are all settings which directly affect the signal path through the transmitter, i.e. settings for the coder, the exciter inputs and outputs, the transmit frequency and the output power. The program‑specific settings are made at the A transmitters and stored using the menu item "Save Preset" in the Task View of the A transmitter. The settings stored for the A transmitters are synchronized with the B transmitter automatically even if the B transmitter was switched off when the settings were stored. If the program‑specific settings are changed at A transmitters without these settings being stored as presets, the changes will not be available on the B transmitter in the event of a switchover. Presets can only be stored on the A transmitters. Configuring Power Specific Settings All settings which have been stored on an A transmitter as presets and synchronized with the B transmitter can be overwritten individually in the B transmitter. This can be used to

System Overview

calibrate the power test points of the B transmitter to the frequency and output power of the respective A transmitter. To do so, the "Program Settings" of the A transmitter concerned must be activated in the B transmitter ("Load Program Settings") and then the corresponding settings must be made menus of("Save the B Tx transmitter. Finally, changed settings must be stored in theinBthe transmitter B Settings"). Thisthe must be repeated for all programs that the B transmitter can take over. Settings that have been changed directly at the B transmitter are no longer synchronized with the B transmitter using the "Save Preset" function on the A transmitters. It is therefore recommended to overwrite the preset settings of the A transmitters at the B transmitter only for purposes of calibrating the power test points, and never to make program‑specific settings directly at the B transmitter. If a setting has been inadvertently changed on the B transmitter and stored for an A transmitter, automatic synchronization can be reactivated for this setting value in the following way: ●

On the B transmitter, set the setting value to the same value as on the A transmitter.

●

Press "Save Tx B Settings" in the menu of the N+1 automatic function

This setting value is now synchronized again together with all program‑specific setting values of the A transmitter "N+1 Automatic" parameters ●

Automatic Switchover Functions

Automatic Input Signal Switchover The R&S®TCE900 in the R&S®TCE900 exciter configuration has an automatic switchover function which, in the event of a signal failure at one logical input, switches over to the other logical input (provided that a valid input signal is available at the other logical

input). Before a failure occurs, the preselected input is active. The way in which this automatic switchover function operates is determined by the following factors:

Automatic input switchover ON/OFF If automatic switchover is OFF, the preselected input remains active even if the input signal fails. If automatic switchover is ON and there is a failure at the (preselected) input, switchover to the standby input takes place. Input priority (Preferred Input = Logical Input 1/2) Following a switchover of the priority logical input to the standby input, the automatic system switches back to this priority input as soon as a signal reappears. All switchover operations are delayed for the set delay times. If the signal fails at both the main input and the standby input, the priority input remains active. Inputs with equal priority (Preferred Input = none) Following a switchover of the active logical input, the second input with the same priority remains active until the input signal also fails on this input. The automatic system switches back to the preselected input, but only if a signal is present on it once again (and if "Switch to" is set to "reserve & back"). All switchover operations are delayed for the set delay times. Selecting this operating mode minimizes the number of switchover operations and, in certain cases, the number of breaks in transmission.

Direction of switchover (Switch to) The "reserve & back" switch position enables switchover in both directions, i.e. to and from the standby input, depending on which of the two logical inputs is currently faulty. The "reserve" switch position ensures that switchover takes place once only. Following switchover, the automatic system switches to "switched" and the "Active" indicator disappears. Switchback to the preselected input takes place when the active input is switched over by pressing the input selector switch (Selector) and then selecting the preselected input.

If the switch is set to "reserve", the switchback to the preselected input is suppressed.

Manual switchover between inputs The input can be switched over in the "Home" > "Transmitter" > "Exciter" menu by pressing the input selector switch ("Selector") and then selecting the desired input. Depending on the configuration and switching state (ON/OFF) of the automatic input signal switchover function, this menu contains either the switch used to change the preferred input or the switch used to switch over the active input. The automatic input signal switchover function is configured in the following way:

Automatic Exciter Switchover The automatic exciter switchover function enables a faulty exciter to be automatically switched over to a functional standby exciter. In the "Exciter Automatic" menu it is possible to switch automatic switchover between two exciters on and off and to select the basic operating behavior of the function. The "Switch Mode" switch is used to select whether automatic switchover to a standby exciter is to take place once only (Single Switch) or whether a switchback is also to be performed if the standby exciter signals a fault, but the preselected exciter is no longer faulty (Multiple Switch). It is also possible to set a guard time which must always expire before a switchover can take place. This prevents unwanted switchover operations resulting from brief fault events.

Transmitter

Operation One of the two exciters can be preselected for operation by pressing the exciter selector switch (or via the ExciterAuto -> Exciter Switch tab). This exciter is switched on together with the output stage by pressing the "Program Path On" switch (in the "Transmitter" menu). If necessary, the RF of the standby exciter can be switched on for measuring and monitoring purposes by pressing the "Reserve Path (on)" switch (in the "Transmitter" menu). A switchover operation causes the standby exciter to become the main exciter and vice versa. The ON/OFF switches then act on the other exciter in each case. "Single Switch" mode If a fault occurs in the preselected exciter, the automatic switchover function will swap the main and standby exciter and display an "Automatic changed" message. Either the new state can now be accepted by changing the "preselected exciter" ("Automatic changed" disappears) the automatic switchover function inal state by pressing "Resetor Faults" (in the "Transmitter" menu). can be reset to its orig"Multiple Switch" mode This mode is identical to "Single Switch", except that following a double switchover operation the "preselected" exciter becomes the active exciter again. The "Automatic Changed" message is still displayed in this case. To delete this message, either the new state of the automatic switchover can be adopted by pressing the "Recommand Selection" button (in the "Transmitter" > "Exciter Auto" menu, "Exciter Switch" tab) or the original state can be assumed again by pressing "Reset Faults" (in the Transmitter menu).

Coders (Standards)

DVB T2

To operate the transmitter in DVB ‑T2 mode, an appropriate software option must be activated using an option code.

This function is used to set the DVB transmission parameters required for coding and modulation and to check the used (TPS) settings (TPS = transmission parameter signaling) that are signaled during transmission. The network configuration parameters are used to set the higher ‑level parameters for DVB‑T2 that comply with the standard and are valid for all physical layer pipes (PLP). The L1 frame information parameters are used to configure the "L1 post signaling". The PLP parameters are used to make various settings for the possible PLPs. When streaming via TS (TS Stream setting), the PLP parameters can be configured for exactly one PLP. If, however, T2MI is active (T2MI = On), several PLPs from the T2MI information can be configured automatically. To display the settings of a certain PLP, the corresponding ID must be entered in the "Viewed PLP" column. Some of the parameters can only be changed if "Network Interface" is set to "TS Stream" in the transmitter. If "Network Interface" is set to "T2 MI Stream", the parameters are set via the DVB‑T2 gateway. DVB T2 Lite To operate the transmitter in DVB‑T2 Lite mode, an appropriate software option must be activated using an option code.

The DVB‑T2 Lite profile is based on the DVB ‑T2 standard with certain parameters removed and a number of specific additions made that are specifically relevant to mobile reception. The Lite profile has been optimized for the use of inexpensive mobile receivers with low energy consumption, but can also be received using conventional DVB ‑T2 receivers. This is achieved by reducing the range of functions of DVB‑T2, thereby significantly reducing the complexity of the respective receiver modules. The DVB‑T2 profile is configured via the DVB‑T2 gateway and activated automatically in the R&S®TCE900 exciter.

4.3.1.2

DVB-T The DVB‑T transmission parameters required for coding and modulation as well as the TPS settings (TPS = transmission parameter signaling) used and signaled during transmission can be checked in the "Configuration" menu field. The DVB‑T standard can be used both in single frequency networks (SFN) and multiple frequency networks (MFN). In SFNs, the transmission signaling parameters (TSP) are usually set automatically by the megaframe information packet (MIP); in MFNs, the TSP parameters are usually set manually. The two variants DVB‑T and DVB‑H are additionally available for both operating modes. In the Localization menu, it is possible to define manually or automatically (via MIP) the SFN cell to which this transmitter is to be assigned. To allow fine adjustment of single‑frequency networks, a time and frequency offset from the data carousel of the MIP can be set individually for each transmitter of the SFN via the central SAN adapter. This is activated by setting Tx Control to "On" and by defining a transmitter address that is unique in the SAN. In the TPS Settings menu, the TPS transmission parameters can be configured manually (only with TPS Source = Manual). The modulation parameters effective in the coder are displayed under "Active TPS Settings" (all operating modes). In the DVB‑H TV standard, a number of other transmission parameters are available. "Configuration" parameters These settings influence the availability of certain parameters in the Modulation menu.

ISDB-T

To operate the transmitter in ISDB-T mode, an appropriate software option must be activated using an option code. The ISDB‑T TV standard can be used both in single frequency networks (SFN) and in multiple frequency networks (MFN). In an SFN, the time at which an ISDB ‑T symbol is transmitted is either set automatically via the ISDB-T information packet (IIP) or set statically at each individual transmitter. The network mode is selected in the SFN menu. If an IIP is present in the feed data stream, all TMCC (transmission and multiplexing configuration control) settings should be performed automatically. In this case, "Coder Source" must be set to "IIP". In the case of operation in a static SFN (in which usually no IIP is present), all coder settings can also be performed manually. In this case, "Coder Source" must be set to "Manual". Depending on this switch, the settings in the "Modulation (Manual)" tab are either effective or not effective. The active (effective) TMCC setting of the coder is displayed in the "Modulation (Active)" tab. With manual setting, the display is identical to the TMCC values set in the "Modulation (Manual)" tab. With automatic setting via IIP, the displayed TMCC settings are identical to the values signaled via IIP. In the Localization menu, certain exciter settings can be controlled automatically via IIP. The following functions are supported: ●

Transmitter ‑specific setting of the time of transmission

●

Setting Transmit Frequency and Output Power The transmit frequency is set separately for each TCE900 exciter with an accuracy of ± 1 Hz. For the DVB‑T and DVB‑T2 transmission standards, the channel center frequency must be set during this process. The output power of the TCE900 exciter is regulated internally to +13 dBm. It can be attenuated via an integrated attenuator by up to 9 dB (in steps of 3 dB). In high‑power and medium‑power transmitters with only one amplifier, an attenuation of 9 dB must be set. In systems with more than one amplifier, an attenuation of 0 dB must be set. The transmit frequency and output power are configured in the following way: ► Using the menu bar, navigate to the following: "Devices" > "Tx" > "Exciter A | B" > "Output"

4.3.3

Signal Feed The TCE900 exciter has a number of physical inputs depending on the modules and software options installed. Up to two of these inputs can be used parallel to each other for signal feed. They are referred to below as logical inputs. The assignment of physical inputs to logical inputs takes place in a special task during startup of the system. All available physical inputs can also be configured within this task. In normal operation, the two selected logical inputs are visible in the Device View of the exciter. All settings rele-

vant for the logical inputs can be made directly in the Device View. The two logical inputs are available for automatic input switchover in the event of a fault along the feed path.

4.3.3.1

Configuring Physical Inputs The physical inputs are configured at startup of the system in the menu "Device View" > "Tx" > "Exciter A | B" > "Task View" > "Configure Inputs". This function defines two logical inputs from the number of available inputs used for the redundancy of the input signal. For each logical input, a name can be optionally assigned for the fed program multiplex. This name is displayed in the transmitter and system overview screens. TS Feed Every exciter which is and suitable forThe the data transmission of digital TV has two transport streamTCE900 inputs (connector X20 X21). format (ASI/SMPTE/Auto) can be set separately for both inputs. The gross data rate and the packet length are also displayed. IP Feed Depending on the installed software options, up to two independent IP feeds are available in the TCE900 exciter. During startup, each Ethernet socket (X30, X31) must be assigned an IP address in the menu "Device View" > "Tx" > "Exciter A | B" > "Task View" > "Configure TS LAN". The two Ethernet sockets are linked to two logical IP streams which contain additional configuration parameters. Both IP streams support unicast and multicast streams. For multicast streams, the IP address of the multiplexer which makes the stream available in the network must also be specified. It is possible to assign both logical IP streams to the same physical socket, but to specify different multicast addresses. This provides maximum flexibility with regard to different redundancy scenarios in the feed path. The IP addresses for the Ethernet sockets are configured in the "Configure TS LAN" task and only become effective after the TCE900 exciter has been restarted.

If a short checkout time is set, the system can quickly switch over to a standby exciter if all input signals of the exciter fail. If a long checkout time is set, there will be enough time in the event of a fault to switch to an alternative feed path so that the exciter is prevented from switching over to a redundancy component.

Input Signal Switchover The R&S®TCE900 in the R&S®TCE900 exciter configuration has an automatic switchover function which, in the event of a signal failure at one logical input, switches over to the other logical input (provided that a valid input signal is available at the other logical input). Before a failure occurs, the preselected input is active. The way in which this automatic switchover function operates is determined by the following factors:

5/27/2018


R&S THU9/TMU9


Automatic input switchover ON/OFF If automatic switchover is OFF, the preselected input remains active even if the input signal fails.If automatic switchover is ON and there is a failure at the (preselected) input, switchover to the standby input takes place. Input priority (Preferred Input = Logical Input 1/2) Following switchover of the priority logical input to the standby input, the automatic system switches back to this priority input as soon as a signal returns. All switchover operations are delayed for the set delay times. If the signal fails at both the main input and the standby input, the priority input remains active. Inputs with equal priority (Preferred Input = none) Following switchover of the active logical input, the second input with the same priority remains active until the input signal fails on this input also. The automatic system switches back to the preselected input, but only if a signal is present on it once again (and if "Switch to" is set to "reserve & back"). All switchover operations are delayed for the set delay times. Selecting this operating mode minimizes the number of switchover operations and, in certain cases, the number of breaks in transmission.

Direction of switchover (Switch to) The "to reserve and back" switch position enables switchover in both directions, i.e. to and from the standby input, depending on which of the two logical inputs is currently faulty. The "reserve" switch position ensures that switchover takes place once only. Following switchover, the automatic system switches to "switched" and the "Active" indicator disappears. Switchback to the preselected input takes place when the active input is switched over by pressing the input selector switch (Selector) and then selecting the preselected input. If the switch is set to "reserve", the switchback to the preselected input is suppressed.

Seamless switching The automatic input signal switchover function has an operating mode which permits seamless switching between two inputs. Seamless switching is activated using the "Seamless" switch. If seamless switching is possible, the switchover always takes place immediately, irrespective of the set guard times. Seamless switching is available without restriction for operation in single‑frequency networks (SFN). For operation in MFNs, it is necessary to set the maximum expected delay time between the two signal feeds. The signal which arrives earlier is delayed by the set time and the signal which arrives later is adjusted to the earlier signal. The currently measured delay between the two inputs is displayed to provide an adjustment aid. In SFN and MFN mode, signals can be fed via two different media (e.g. ASI and IP).

4.3.4 Controlling Time of Transmission in Single-Frequency Networks (SFN) For operation in single-frequency networks (SFN), the R&S®TCE900 exciter has a function which allows the time at which the signal is transmitted to be controlled. In the SFN, time synchronization of all exciters in the network is performed using a seconds pulse (PPS), which is generally obtained at the exciter site via GPS satellites. Controlling time of transmission Control of the time of transmission is switched on and off in the "Device View (Home)" > "Transmitter" > "Exciter" > "SFN Regulation" menu ("Time Synchronization" tab) by means of the "SFN Sync" switch (On (SFN) / Off (MFN)). This function can only be used if the exciter has a time reference (exception: ISDB‑T Static SFN). The following options are available: ●

Feed of an external PPS signal (pulse per second)

●

Use of an integrated GPS receiver (requires option key)

If the time reference fails during operation, the exciter can revert to its integrated frequency control function (see the chapter "Frequency Control") and calculate a highly

precise PPS internally. To do so, the exciter only needs to be able to synchronize with a PPS once for a few seconds after it has started. If the time and frequency reference fail at the same time, Holdover Mode becomes active. In this operating mode, the accuracy of "time of transmission" control depends on the frequency stability of the integrated, temperature‑stabilized 10 MHz crystal oscillator (OXCO). Since, in Holdover Mode, calculation of the time of transmission becomes increasingly inaccurate over time, the output signal of the exciter can be switched off after a configurable Guard Time. Special points with ISDB T With ISDB‑T, three different operating modes are supported. ●

Dynamic SFN The time of transmission of the signal for all transmitters in a single‑frequency network (SFN) is controlled relative to a common seconds pulse.

●

Static SFN The time of transmission of the signal is set statically for each individual transmitter. The delay time on the feed path must be constant.

● Auto The operating mode (Dynamic SFN or Static SFN) is set automatically using transmitter ‑specific information in the IIP (ISDB ‑T Information Packet).

Special points with ATSC With ATSC, up to three different synchronization types are supported. The respective synchronization type must be enabled by means of a corresponding software option. ●

R&S Mobile If mobile content is transmitted and a R&S®AEM100 Emission Mux/SFN inserter is used, the "RSMobile" synchronization type must be selected.

●

R&S A53 If normal content is transmitted and a R&S®AEM100 Emission Mux/SFN inserter is used, the "RSA53" synchronization type must be selected.

● A/110 In the case of the standard‑conforming SFN synchronization corresponding to ATSC A/110B, the "A/110" synchronization type must be selected. It contains a compatible

expansion to allow use of Mobile DTV. With the synchronization types "R&S Mobile" and "A/110", a distinction is also made as to whether the time of transmission is to be synchronized primarily using data from the TCP information or using data from the dummy bytes. Setting and display of time of transmission In the "Device View (Home)" > "Transmitter" > "Exciter" menu ("SFN Delay" tab), the time of transmission is displayed relative to the reference time. The time of transmission can be adapted individually by setting an additional static delay. The following delays occur:

4.3.6 Precorrection Each TCE900 exciter is equipped with an adaptive precorrector that continuously compensates for nonlinear distortion of the amplifiers and linear distortions of the output filter. As a result, in both cases a high‑quality signal is present at the output of the transmitter. Adaptive nonlinear precorrection For adaptive nonlinear precorrection, enter a minimum shoulder distance that must not be undershot. The precorrector will calculate a new precorrection curve as soon as a shoulder distance below the set value is measured. The adaptive precorrection can be stopped if necessary (Adaptive Predistortion = Stop). The current precorrection curve remains in effect. For measuring purposes, the adaptive nonlinear precorrector can be bypassed (Adaptive Predistortion = Bypass) so that the TCE900 exciter returns an undistorted signal at its RF output. The precorrector can be restarted manually (Reset), making it possible to calculate a better precorrection curve, even if the shoulder distance has not yet been undershot. The current precorrection is lost as a result. Adaptive linear precorrection With adaptive linear precorrection, limit values for amplitude (Amplitude Ripple) and group delay (Group Delay Ripple) must be set. The precorrector will calculate a new precorrection curve as soon as the limit values are exceeded. The adaptive precorrection can be stopped if necessary (Adaptive Predistortion = Stop). The current precorrection curve remains in effect. For measuring purposes, the adaptive linear precorrector can be bypassed (Adaptive Predistortion = Bypass) so that the TCE900 exciter returns an undistorted signal at its RF output.

Crest factor reduction Available as an option for all COFDM standards The crest factor feature provides the possibility of improving the signal parameters "MER" and "Shoulder Distance" separately. Additionally, the signal can be improved and the DC supply voltage reduced at the amplifier to increase efficiency; this simultaneously reduces the crest factor of the transmitter. Sound phase shifter Only available for analog TV standards The sound phase shifter modifies the phase of the sound subcarrier as a function of the low-frequency modulation of the picture signal. When the sound phase shifter is switched on, its characteristic curve is determined using two onset points. The reference for setting the position is initially a value of 37.5 % for the back porch. Smaller values are in the range of the sync pulse; a value of 15 % corresponds to a

‑

sync pulse amplitude of 300 mV. Larger values are in the picture range; a value of 90 % corresponds to a picture amplitude of 700 mV. An additional condition is that the setting for onset point 1 must always be greater than that of onset point 2. The sharpness of the two onset points is determined by the slope of the characteristic curve at these points. The magnitude of the setting determines the magnitude of the phase shift, whereby a setting of 50 % specifies the maximum value. The sign of the setting value determines whether the phase is shifted in the positive or negative direction. When the characteristic curve is calculated, it is divided into three linear areas by the two onset points. No takes for modulation picture signal in the area between the twophase onset shift points, i.e. place a correction phase ofof 0°the is set. A correction phase unequal to 0° is set in the case of picture signal modulation that is greater than the position of onset point 1. The characteristic curve in this area begins with a correction phase of 0°, with modulation corresponding to the position of onset point 1, and increases linearly up to the maximum phase set with slope 1, with 100 % modulation of the picture signal. Similarly, a correction phase unequal to 0° is also set in the case of picture signal modulation that is smaller than the position of onset point 2. The characteristic curve in this area begins with a correction phase of 0°, with modulation corresponding to the position

5.3.1.1

Simple Network Management Protocol (SNMP)

General Simple Network Management Protocol (SNMP) is used for monitoring and controlling different units in a network. A description of the unit – the management information base (MIB) – must be loaded in the central unit ("manager") from which the transmitters are monitored. A monitored unit contains a program ("agent") which can answer queries from the manager and execute commands. Furthermore, the agent may of its own accord generate a message (called a notification, alarm or trap) and send it to the manager. In this way, the central unit can be informed of a fault. The MIBs required for monitoring and controlling a transmitter are stored as a ZIP archive in every R&S TCE900. From there, they can be downloaded with any web browser. When the transmitter is put into operation, both the agent in the transmitter and the manager must be configured. Additional steps may be necessary if the transmitter is connected via routers, firewalls or similar devices as they may block data packets.

5.3.1.2

Settings on Transmitter Side You can make settings yourself via the local R&S TDU900 display (if available), the web server or SNMP. The Task View > System Control > SNMP menu contains all the settings that are required for accessing a transmitter. Changes to these settings are adopted immediately. The instrument does not need to be restarted.

Fig. 5-1: SNMP menu.

The XX9 transmitter family supports the versions SNMPv1 and SNMPv2c. Alarms can be sent as v1Traps, v2Traps or v2Informs. Several destinations for error messages (trapsinks) and several communities can be set with read only authorization and read/ write authorization. SNMP is a protocol for remote control and is offered only at the remote Ethernet interface (X2 – 1000 BaseT). The system or transmitter has to be set to remote to execute SET commands. 5.3.1.3

Settings on Manager Side The basic SNMP settings (port, community) have to match on the manager side and transmitter side. You typically define these settings for each IP address in your program (e.g. MIB browser). The SNMP version is also set in the manager; the transmitter then detects this automatically. Subsequently, SNMP communication should already be functioning at a basic level.

A detailed description of the MIBs, the information that they contain and the associated options is given below. MIBs from Rohde & Schwarz and IRT are available. MIBs from IRT allow transmitters to be linked using SNMP irrespective of the manufacturer. They are, however, limited with respect to their functionality. Some particular features to keep in mind when using IRT MIBs are listed in the document "SoftwareMiniSpecification – SNMP for XX9". The MIBs have the naming convention RS-XX9--MIB. Examples include: RS-XX9-DVBT2-MIB for DVB-T2 and RS-XX9-AIR-COOLINGMIB for air cooling.

Which MIBs Must be Used? The instrument can be queried by SNMP in order to find out which MIBs have been implemented. This information is contained in the table "sysORTable" (OID .iso(1).org(3).dod(6).internet(1).mgmt(2).mib-2(1).system(1).sysORTable(9) of the SNMPv2 MIB). There is a corresponding MIB for each type of modulation.

MIB

Description

RF-XX9-COMMON-MIB

This MIB contains general data that supports every unit: - Transmitter configuration, option keys, SNMP configuration software update, triggering a test notification: This information always applies to the instrument monitored using SNMP.

RF-XX9-TX-MIB

This MIB contains parameters independent of the type of modulation for: - The standby concepts "single transmitter", "passive exciter standby", "active output-stage standby" - all power classes (medium-power and high-power).

RF-XX9-MAX-MIB

This MIB contains parameters independent of the type of modulation for: MultiTx ● N+1 ●

RF-XX9-LIQUIDCOOLING-MIB

This MIB contains parameters for liquid-cooled transmitters, either with internal Rohde & Schwarz cooling or with (external) station cooling.

RF-XX9-AIRCOOLING-MIB

This MIB contains parameters for air-cooled transmitters.

DRS-XX9-DVBTMIB

This MIB contains parameters for DVB-T signal processing.

RS-XX9-DVBT2MIB

This MIB contains parameters for DVB-T2 signal processing.

Which OIDs from a MIB Must be Used? Different parameters are available depending on the system being queried. Thus for example txExcAutoOperationMode (in RS-XX9-TX-MIB) returns the response NoSuchName when you query a single transmitter, since it has no automatic exciter switchover. It easy to findfor outautomatic which parameters are valid by checking thetxExcAutoOperationMode conformance statements. Inis the example exciter switchover above, the OID is contained in the txObjsExciterAutomatic object group. For N+1 systems this also means that unavailable parameters may receive the response NoSuchName, e.g. parameters from the transmitter A8 if only a 4+1 system is present..

Setting Alarms Parameters which allow configuration of the transmitter alarms can be found under the OID "commonSnmpConfiguration". For example, it is possible to switch off the IRT alarms (factory default setting: on) and to switch on R&S alarms (factory default setting: off). The transmitter-specific alarms offer an extensive range of configuration possibilities. In addition, it is also possible to assign a freely selectable priority and to check the current status. Since the Rohde & Schwarz MIBs contain a very large number of alarms, three predefined groups for faults, warnings and information exist to which all alarms are assigned. For each alarm, the respective alarm class is given in the binding AlarmClass. A possible and recommended configuration would therefore be to disable the IRT alarms and to enable the Rohde & Schwarz alarms of the fault class:

Matching the alarms, there are one or more NotificationTables in the MIBs on the Objects branch. Information is displayed together there. 5.3.1.7

Testing the SNMP Communication In the following example, a transmitter with the IP address 172.29.12.43 queries the OID sendTestNotification (1.3.6.1.4.1.2566.127.1.2.216.2.1.3.1). The response from the agent is "idle(1)". Using a further test, you can check whether the transmitter sends an alarm message in the event of an error and whether this message reaches the alarm destinations. To do so, set an OID sendTestNotification to the value of 2 (trigger), which triggers a commonTest trap (1.3.6.1.4.1.2566.127.1.2.216.2.0.1000). This alarm is sent to all receivers which have been entered for the alarms (trapsinks, see above). This type of error message functions in a slightly different way than that used for querying and setting values (default: UDP Port 161 for SET/GET and UDP Port 162 for alarms). The following image shows that the testTrap has been received correctly by the tce900-100100 unit (serial number 100100).
