This test measures the maximum leveled power available from the PNA source across the frequency range of the PNA, and verifies the maximum power listed in the Test Port Output – Power Range specification. The test is performed at many CW frequencies across the frequency range of the PNA.
In the Normal Variant test plan, a separate test has been created for frequencies above 50 GHz to avoid unnecessary recalibration of the power sensors. Because of the measurement process, Sources Unleveled messages are expected on the PNA display during this test.
The measurement uncertainty for this test only applies to the power meter measurement. The measurement process does not identify the precise maximum power for a given frequency. The measured value is within a 0.1 dB window below the precise maximum power.
When the actual power is more than 5 dB above the test limit, the reported max power may be less than the actual max power. This difference is caused by the limited power range of the power sensor.
