10.Press Freq, 322.5 MHz, Span, 1 MHz, Peak Search on the functioning
11.The analyzer should read 322.5 MHz at −30 dBm ± 3 dBm as shown in
Figure 7-3 A13 322.5 MHz Output
If the 322.5 MHz signal is not measuring the correct power level, refer to
Section Troubleshooting (RF/Microwave Analyzers)."
Reconnect W15 at A13J7.
Measuring at this location is for convenience. The 322.5 MHz signal is an
IMPORTANT
output at A13J7. Since the W15 cable connects from this output to the input
of the Analog I.F. assembly at A2J100, the small coaxial cable has not been
tested at this point. If the analyzer is equipped with any combination of
options CR3, CRP, 532, or 544, the 322.5 MHz signal will also be routed from
A13J7 to A15J902 via W36 and from A15J900 to A2J100 via W37.
