Deenergize DC power supply. j. Before connecting the UUT to the test setup, verify that the DC power supply is deenergized. k. Connect the UUT to the test setup lAW Figure D-29. M129-18 Figure D-29. Power Supply Module Adjustment Setup D.6.11.4.2 Antenna Output Adjustment Procedure. The purpose of this adjustment is to calibrate the antenna power output voltage to the operating power of the specific transceiver P/N AY6706557-0. This test is performed whenever the power supply module is combined with the transceiver and/or after replacing the transceiver itself. a. Connect points TP1 and TP2 in the test equipment to R15 and anode of CR12 in the tested unit (see Figure D-29.). b. Energize all test equipment. c. Set switch S1 to position ANT POWER. d. Record in the adjustment test data sheet, the desired voltage of the transceiver and its serial no. e. Turn on ANT S.D. switch. f. Verify voltage measure on DMM1 is 10±1 Vdc. g. Calibrate voltage measurement in DMM1 using PR1 in test equipment until the DMM1 shows the desired voltage for the transceiver is V ± 0.1 Vdc. D-74
