This part of EN EN 50561 specifies limits and methods of measurement of radio radio disturbance characteristics for in-home communication apparatus that use the low voltage power installation as the transmission medium. This part of EN50561 EN50561 applies to equipment equipment that uses frequencies including those above 30MHz in order to communicate.
Scope
Equipment communicating exclusively in the frequency range from 1,6065 MHz to 30 MHz is covered in in EN 50561-1. The requirements requirements specified in this document are applicable for apparatus using frequencies of transmission up to 87.5 MHz. NOTE: a signal level mask will ensure sufficient decay to adequately protect the reception of radio services (see figure 1).
Procedures are given for the measurement of signals signals generated by the equipment and limits limits are specified for the frequency range 9 kHz to 400 GHz. No measurement is required at frequencies where no limits are specified.
