D.4.13.3 TRANSMITTED POWER FAILURE. Failure in test procedure para. D.4.12.2.5.
a. Repeat the test procedure. Verify proper RF power meter setting and calibration. Verify service-
able RF cables are used.
b. If no power or power out of specified range, replace transceiver.
D.4.13.4 RECEIVER SENSITIVITY FAILURE. Failure in test procedure para. D.4.12.2.6.
D.4.13.4.1 Sensitivity below required level.
a. Repeat the test procedure. Adjust phase shifter.
b. If no broad band noise, test and troubleshoot Doppler amplifier CCA lAW Section D.5.
c. Check ripple voltage of no more then 50mVp-p on transceiver oscillator input. If failed, test and
troubleshoot power supply module lAW Section D.6.
d. If broadband noise is higher then allowed, replace transceiver.
e. Set variable attenuator to 10dB attenuation. If signal on Doppler amplifier CCA outputs is
saturated, 12Vp-p or more, replace transceiver.
f.
If not failed, test and troubleshoot Doppler amplifier CCA lAW Section D.5.
D.4.13.4.2 No Sensitivity.
a. Set variable attenuator to 30dB.
b. Check shielded wire on Doppler amplifier input.
c. Check ripple voltage of no more then 50mVp-p on transceiver oscillator input. If failed, test and
troubleshoot power supply module lAW Section D.6.
d. If no output noise at all, test and troubleshoot Doppler amplifier CCA lAW Section D.5.
e. If there is some output noise, replace transceiver.
D.4.13.4.3 Signal On One Output Only. Test and troubleshoot Doppler amplifier CCA lAW Section D.5.
D.4.13.5 INTEGRATED SIMULATOR FAILURE. Failure in test procedure para. D.4.12.2.7. (For versions
AY6707292-4 and AY6707292-5 only)
a. Replace integrated simulator assembly.
b. If failed after replacement, replace microstrip antenna.
D.4.13.6 POWER CONSUMPTION FAILURE. Failure in test procedure para. D.4.12.3.4.
D.4.13.6.1 No Current Consumption.
a. Remove connector P3 from MVP CCA. Check for correct voltage between pins 1.3.2 and 2 of
connector P3 (28Vdc). If failed, replace EMI filter module lAW Section D.8.
b. Check for continuity between pin P12.3/ito pin P3/1, and pin P1/2 to pin P3/2, of connectors P1
and P3 of the MVP CCA. If failed, test and troubleshoot MVP CCA lAW Section D.7.
D.4.13.6.2 High Current Consumption.
a. Remove connector P3 from MVP CCA. Check for continuity between pins 11 and 12 of connector
P3 to pins H and K of J1 respectively, of EMI filter module. If failed, replace EMI filter module lAW
Section D.8.
b. Check for continuity between pins 11 and 8 of connector P3 of MVP CCA. If failed, test and
troubleshoot MVP CCA lAW Section D.7.
c. If not failed, test and troubleshoot MVP CCA lAW section D.7 for high correct consumption.
