NI SCOPE Card Fails Self Test with Internal Hardware Error

Updated Jan 6, 2021

Reported In


  • PXI Oscilloscope


  • Measurement & Automation Explorer (MAX)



Issue Details

I have a National Instruments PXI Oscilloscope card and my device fails the self-test in NI Measurement & Automation Explorer (MAX) with one of the error codes below:
  • -239000
  • -239001
  • -239020
  • -239022
  • -200550
  • -228858
  • -200313

An example of the error message I see along with the code is listed below:

Error -239000 occurred at Self Test

Possible Reason(s):
Internal Hardware Error occurred in MIG hardware. Please contact National Instruments Support.



These error codes indicate fairly general problems that can be caused by either hardware or software. You can resolve these errors through one of the troubleshooting steps below:
  • Reset the device in Measurement & Automation Explorer, then try the self-test again.
  • Reboot the PC or PXI controller.
  • Try a different PCI or PXI slot.
  • Reset your NI MAX configuration database.
  • Reinstall the device driver in Windows Device Manager (you don’t need to reinstall NI-SCOPE) by deleting or uninstalling the device and letting the operating system re-detect the hardware (Action>>Scan for Hardware Changes in Windows Device Manager).
  • Update the driver to the latest version that supports your application development environment and operating system. This information can also be found within the Readme documentation for each version of the driver. Note: The Readme is located on the driver download page .
  • If possible, try the card in a different system.
  • If you are using the module with an MXI system, kindly ensure the BIOS is compatible with MXI. Installing MXI-Express BIOS Compatibility and perform the installation instruction mentioned in its Readme file might solve this issue.
If you try all of the steps above and your device still fails self-test, please contact National Instruments Support.
