Review the General Troubleshooting recommendations before proceeding with this section.
Source unlevelled errors are expected as part of the test process. These errors do not indicate a problem with the PNA.
Power meters with firmware version A2.03.00 or A1.03.00 may not operate properly with the new test software. Upgrade the power meter firmware if necessary.
A failure in this test may indicate a need to correct the source flatness. This is accomplished by performing the Source Calibration Adjustment.
Prior to running this test, certain settings must be set on the PNA to avoid error messages and possible test failure.
If an error occurs on PNA B-models, make sure that the Power Report source unleveled events as errors is not selected in the Preferences menu. On the PNA, go to Utility > System > System Setup > Preferences... and make sure that the setting is unselected (has no check mark).
Make sure that the PNA Power Limit setting is set to OFF. Although the default state for this setting is OFF, some customers may have changed this setting. To verify that the setting is in the OFF state, on the PNA go to Power > Power and Attenuators > Offsets and Limits. From the drop-down, select OFF for all ports. Verify that the state for all ports shows as OFF.
