Dynamic Accuracy — Factory Recommended Variant

Equipment and Setups

This test applies to the following models using the Factory Recommended Variant test plan:

This test is extremely sensitive. To minimize the chance of test failure, it is important to follow proper testing procedures:

  • On the PNA, go to Utility > System > System Setup > Preferences. Ensure that this setting is NOT selected: Marker: Coupling controls on/off state of markers.
  • Ensure all connectors are clean.
  • Properly torque all connections.
  • Check that all test equipment is attached to the correct connecter and has solid connections.
  • Ensure that the required equipment is being used.

  • 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 models with Low Frequency Extension option (LFE), there is an additional test procedure. Refer to the Dynamic Accuracy at Low Frequency topic page.

  1. Refer to the main Required Equipment table for a list of available adapters and cables.
  2. Requires power meter with USB ports.
  3. Not allowed with models with Low Frequency Extension (LFE) options.
  4. If needed, the GPIB address on the test set can be modified by following these steps ().
    1. Connect the new test set to the LAN.
    2. Open Keysight IO from the PC.
    3. Select Add Instrument from the menu.
    4. In the Add LAN Instrument window, locate the new test set on the LAN.
    5. Select the web page for the new test set and select the View & Modify Configuration tab at the left.
    6. Select Modify Configuration.
    7. Change the GPIB address and select Save.

    The new test set should now have the updated GPIB address.

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 PNA mm-Wave Systems N5290A and N5291A, .

 

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.

For the two cables between the power splitter and attenuators, choose short but flexible cables. For best results, the cable between the attenuator on channel 1 of the function generator and power splitter should be of longer length than the cable from the attenuator on channel 2.
