Software

  • InstrumentStudio

Driver

  • NI-DCPower

I encounter an issue that when I use PXIe-4139 in InstrumentStudio and set mode to "Pulse Voltage". There is an error which message is  “ Value is not supported”. How can I fix the error?

This is an bug of PXIe-4139 from DCPower 24Q4 to 25Q2 and the bug  is fixed in 25Q3. If other module also encounter same error, update driver to 25Q3 or downgrade drvier before 24Q4 will fix the issue.
