Figure 7-2
A13 322.5 MHz Output
Reconnect W15 at A13J7.
IMPORTANT
Measuring at this location is for convenience. The 322.5 MHz signal is an
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 322.5 MHz signal is not measuring the correct power level, refer to
Chapter 4, “RF Section Troubleshooting (N8973B, 74B, 75B Analyzers)”

this service guide.
