Why Can't I Communicate with My GPIB Instrument?
The answer to this question depends on the type of behavior you are seeing. The following topics describe some common problems and their solutions. You may be trying to communicate with your instrument from Measurement & Automation Explorer (MAX), using Interactive Control (IBIC), LabVIEW, LabWindows/CVI, or another application program. Usually, to establish basic communication, you are trying to write to your instrument and then read some useful data from that instrument.
