g. Set switch S1 on the test fixture to PS position.

h. Set ANT S.D. switch on the test fixture to OFF position.

i.

Energize and adjust DC power supply to measure +28±10 Vdc. Deenergize DC power supply.

j.

Before connecting the UUT to the test setup, verify that the DC power supply is deenergized.

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.
