Dynamic Accuracy Troubleshooting

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.
Because of the sensitivity of this test, it is recommended to leave the power sensor undisturbed and connected to the Dynamic Test Set for at least 30 minutes prior to running the test.

Review the General Troubleshooting recommendations before proceeding with this section.

This troubleshooting procedure assumes the PNA successfully passes the System Crosstalk test (if applicable) and the Noise Floor test.

If a phase lock lost error occurs during the test, it may cause the test to fail. Phase lock problems should be fixed before further troubleshooting. If the test fails or is in an indeterminate state, rerun the test.

There are no adjustments for an analyzer which fails the Dynamic Accuracy Performance Test.

Refer to the appropriate PNA service guide for specific troubleshooting suggestions and replacement procedures.
