Troubleshooting
Connect W16 cable output to a functioning spectrum analyzer and verify the
322.5 MHz intermediate frequency is measuring
−
20 dBm
±
3 dB using the
same analyzer settings as in
.
Figure 4-3
322.5 MHz Intermediate Frequency
If this power level is correct the signal path from the A9 50 MHz Reference
signal input port to W16, IF Output is operating correctly using a 50 MHz input
calibrator signal. Reconnect the W16 cable to A15J902.
Flatness issues or power level problems at other input frequencies below 3600 MHz may exist.
This type of problem can be diagnosed using an external source to verify performance
