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

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

• Traces A, B, R1, and R2 are displayed in four separate data windows as shown in the
representative display in
