Maximum Output Power Performance Test

(N5290A, N5291A)

Prior to running this test, certain settings must be set on the PNA to avoid error messages and possible test failure. Refer to Maximum Leveled Power Troubleshooting for more information.

Test Description

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.

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.

For troubleshooting help, see Maximum Leveled Power Troubleshooting.

Connection Setups

Due to the complexity of the PNA family of analyzers, the following notes apply to illustrations in the PNA Help:

  • Only a single representative PNA model will be shown. Therefore, port locations may differ in older PNA models than what is shown in the illustration. Refer to the port labels on the UUT.
  • Some illustrations may differ than those in TME.
  • If the test procedure applies to multiple ports, illustrations may show the setup on only one test port.
  • Setups for some option configurations may not appear in the Help.

Flexible power sensor channel assignment

This test will use flexible power sensor channel assignment that will identify the channel that a power sensor is connected to using the ability of "smart" sensors such as the N848xA and U848xA series to report their full model and serial number. Therefore it is important to keep the power sensor on the channel where it was calibrated throughout the test procedures.
