Noise Floor — Factory Recommended Variant

Equipment & Setups

  • Before starting this test, verify that the Report Receiver Overload box is un-checked (off). To check the status of this setting, from the PNA menu, go to Utility > System > System Setup > Preferences...

    Scroll down to the bottom of the selections. Be sure the box is un-checked (off).

  • Be sure that ClosedPause on test point fail is not selected for this test.

This topic shows the required equipment and connection setups for PNA models running the Factory Recommended Variant test plan. For more information about test plan variants, refer to the Test Plan Variants topic.

For test description, go to the topic's Overview page.

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.

Setups are grouped by PNA model numbers. Click on the links below for the appropriate model being tested.

For PNA mmWave Systems N5290A and N5291A, .

 

Flexible power sensor channel assignment

PNA models running the Factory Recommend Variant 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.

For more information about test plan variants, refer to the Test Plan Variants topic.

For default front and rear cabling between the PNA and the test set, refer to Step 2: Prepare the PNA for Testing of the Getting Started Guide.
