Keysight CalPod Support Information

 
calpod (25K)


The Keysight 855xxA/B Series CalPod eliminates errors due to cable or test system stability and operates end to end on very long cables which simplifies the process of recalibrating the PNA or PXI M937xA series VNAs without requiring the removal of the Device Under Test (DUT) or the physical connection of standards. This allows recalibration from a remote location such as when the DUT is in a temperature chamber.

Note: The 855xxB Calpods require A.13.25.x.x firmware and above.

Keysight 855xxA/B Series CalPod Models:
  • Keysight 85530B 20 GHz CalPod (Standard)
  • Keysight 85531B 20 GHz CalPod (Temperature Characterized)
  • Keysight 85532B 20 GHz CalPod (TVAC)
  • Keysight 85540A 40 GHz CalPod (Standard)
  • Keysight 85541A 40 GHz CalPod (Temperature Characterized)
  • Keysight 85542A 40 GHz CalPod (TVAC)
Each Keysight 855xxA Series CalPod is controlled with the Keysight Technologies 85523B CalPod Controller.

    Question 1:

    I have lost the USB flash memory containing the thermal characterization data for my CalPod, how do I replace it?

    Answer: Contact csg.servicedesk@keysight.com for assistance.

     


    Question 2:

    How do I delete a thermal CalPod from the list of available CalPods in the CalPod Setup dialog box?

    Answer: Instructions are in the PNA built-in help system.  To access the instructions go to the CalPod dialog box (titled "Calibration Refresh Module Configuration") then click the Help button to access the PNA built-in help system.  Scroll to the information for the CalPod Setup dialog.

     


    Question 3:

    What are the restrictions on PNA calibrations types supported by CalPods?

    Answer: See "Calibration Types Not Supported by CalPods" in the reference section of the CalPods User's Guide.

     


    Question 4:

    How do I use more than two or four CalPods?

    Answer: The basic CalPods configuration described in the CalPod User's Guide assumes no more than one CalPod module per PNA port.  See Using More Than Four CalPods for additional information.


     


    Question 5:

    Where can I get information on the CalPod Operational Check?

    Answer: The CalPod Operator's Check described in the PNA Online help.  See Troubleshooting CalPod OpCheck Failures for additional user information.

     


    Question 6:

    How do I troubleshoot suspected failures in CalPod hardware?

    Answer: Use the CalPod Operator's Check described in the PNA Online help.  It covers both the controller and individual modules.  See Troubleshooting CalPod OpCheck Failures for troubleshooting information.

     


    Question 7:

    What service is available for CalPod hardware?

    Answer: There are no specifications for the CalPod modules or controller.  CalPod hardware does not require annual calibration.  When the CalPod Operator's Check indicates a hardware failure, the failed hardware should be returned to Keysight.  Failed modules will be replaced if under warranty.  Repair of individual modules is not supported.  Repair of CalPod controllers is supported.

     


    Question 8:

    What is the function of the Correct Power check box?

    Answer:

    The Correct Power check box allows the CalPods software to correct for path loss introduced following CalPod initialization.  When a recorrection is performed, the change in path loss between the PNA port and the CalPod module is calculated.  The CalPod software attempts to adjust the output power at the PNA port to compensate for any change so that the power output level at RF2 of the CalPod module remains approximately the same.  (See the PNA on-line help for additional information.)

    To accomplish this function, a Source Power Cal on the PNA port is created if one is not already present.

    If an Unleveled Source message appears on the PNA screen, the PNA source does not have the required power range to compensate for the change in path loss.  An unleveled source may affect the accuracy of the calibration, so it is recommended to uncheck Correct Power when this condition occurs.
