WARNING

Do not point the radiating surface towards any personnel. Do not bring eyes to

close contact with the radiating surface. Use absorbing materials in front of the

radiating surface whenever possible.

D.4.12.3.4 2.3.4 Power Consumption Test. Refer to para. D.4.12.3 3.6 for troubleshooting procedures.

a. Turn on the PC.

b. Load MVS software SPC1553.EXE and run it on the PC.

c. Turn on power supply.

d. Verify current measure on power supply 12.350 to 300mA.

D.4.12.3 2.3.5 Transmitted Frequency and Measure Command Test. Refer to para. D.4.13.7 for trouble-

shooting procedures.

a. Turn on frequency counter and set to measure a 1.70GHz frequency range.

b. Place the standard gain horn in front of the transceiver. (Radome side pointing to the standard

gain horn).

c. Press and hold the ACCL. Switch on the test cable, for approximately 30sec and perform para. d.

through h.

d. Verify current from power supply is 500 to 700mA.

e. Verify frequency measurement on frequency counter is 1.70525±1 MHz.

f.

Verify on the oscilloscope that the receiver noise is 0.5Vp-p to 2Vp-p.

g. On the Test Doppler Simulator, set switch P.S.IBAT to BAT position.

Adjust the Doppler Simulator on the Transceiver to get the maximum signal on oscilloscope.

NOTE

h. Verify the signal on the oscilloscope is:

(1) 8Vp-p minimum. The signal shape is approximately a triangle wave due to EMI filter effect.

(2) (2) 455sec period.

i.

Release ACCL. Switch.

j.

Verify current from power supply is 150 to 300mA.
