Hello,
I have an HP 5350B frequency counter and I have been working with it for automating some measurements. It has an HPIB port on the rear of the cabinet. This is the only instrument connected to the computer at this moment. When I go to NI measurement and automation explorer and scan for instruments I get multiple instruments instead of one (as shown in the screenshot attached). Also none of these detected instruments seem to understand the '*idn?' command as it gives an error while reading from the instrument.
What can I do to establish communication with this instrument?
I would really appreciate comments on this.
Thank You,
Vivek
