Displayed Average Noise Level Troubleshooting

Review the General Troubleshooting recommendations before proceeding with this section.

If any error messages occur on the PNA during this test (such as a timeout error message), run the IF Response Adjustment.

This adjustment is run from the PNA menu:

Utility > System > Service > Adjustment Routines > IF Response Adjustment

Note that for the mm-Wave systems (models N5290A and N5291A), this adjustment is called "IF Response Adj for mm Mode".
