Figure 6-23 IF Inputs
1. Connect a BNC cable to the 20 MHz Out on the rear panel of the
HP 85102 and to the service adapter. Connect the service adapter to the
port 1 module interface.
2. A 20 MHz signal is routed from the HP 85102 through the service
adapter and injected into the a1 and b1 inputs of the module interface, as
shown in Figure 6-23 on page 6-40. Check the a1 and b1 user
parameters for port 1. The traces should be flat lines approximately
- 5 dB across the band (on the HP 8510 CRT).
3. Repeat steps 1 and 2 for the user parameters a2 and b2 at the module
interface at port 2.
