4.3 Final test (receiverand transmitter test with ATTSsoftware) The TRX AutomaticTest System( ATTS) controls the Racal tester via GPIB interface.The test sequencesare createdand startedvia GPIB in Racal . The ATTSsoftwaremonitorsthe executionof the test casesin the Racal tester and gives finally the final results of the test. Power-up and initialization(BTS, Racal 6113 ) : • BTS Switch: PWSBDC PowerSwitch • Automaticreleaseof TSGBSW loading • In BTSBTSSW BTS SWManagerunder Managerunder " Use Current CurrentSW" SW"st start art (takes takesup to test test ≤ 3 min) min) • Whenthis pin appearsthen all TSGBassembliesreadyfor testing The installedsoftwareis displayedin the BTS ManagerBTSSW "SWVersion".
