Issue Details

I have some GPIB Instruments that I am trying to control from LabVIEW. However I receive unexpected measurements and results when I send them certain commands. 

Solution

There are several reasons that could cause this issue:
  • The unexpected measurements could be caused by noise in the GPIB system.
  • The cause could be programming errors in the LabVIEW code. In order to determine if this is the case you can use the GPIB Analyzer to monitor the bus activity and determine if the responses of the instruments are according as expected. 

Additional Information
