The 10.7 MHz is orginated from the A16 Receiver. It is down converted to 700 kHz
±50kHz within the Global Test and Demod assembly. To obtain a reading either with an
oscilloscope (See Figure 4-2 on page12-16) or spectrum analyzer, the signal needs to be
looped back. This can be done using the RF diagnostics and pausing on test #1 for
Receiver Down converters (with spectrum analyzers).
If the generator path is in doubt, use a known working reference signal into a port,
remembering to check settings on RF analyzer page for frequency and port settings.
