Verifying the A, B, R1, and R2 Traces (Standard S-Parameter Mode)

There is no way to view the frequency offset receiver response (Option 080).
NOTE
However, some standard S-parameter receiver trace information is helpful in
troubleshooting the frequency offset section of the PNA. It is therefore
recommended that you run this test even if you only suspect the frequency
offset section of malfunctioning.
The first step is to verify that the A, B, R1, and R2 traces are present and that they are
approximately level:
• On the menu, point to
System
• Traces A, B, R1, and R2 are displayed in four separate data windows as shown in
Figure 4-9. Identifying discrepancies of the traces in these windows can help you to
isolate the faulty assembly.
