Receiver Compression — Factory Recommended Variant

Equipment and Setups

  • This topic is also for the Receiver Compression at Low Frequency test.

  • 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.

 

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.

Power Sensor Calibration Setup

 

For solution using a compression test set, :

 

The Receiver Compression Above 50 GHz test will also test on the 50 GHz – 67 GHz ports of the test set.

  1. calibrate source

  2. measure compression

 

Notes for test process on the:

N5242A/AS/B, N5244A/AS/B, N5245A/AS/B/BC, N5247A/AS/B/BC
N5224A/AS/B, N5225A/AS/B, N5227A/AS/B with Option x01, x17, or x019

  • This test process is modified to measure the compression at the A IN or B IN direct receiver access points.

  • There are two additional test steps to measure the coupling factor for the appropriate coupler.

 

  1. measure the coupler loss 1

  2. measure the coupler loss 2

  3. calibrate source

     

  4. measure compression

 

For Receiver Compression at Low Frequency, :

  1. calibrate source

  2. measure compression 1

  3. measure compression 2
