Tektronix 2784

[MWB500]

I have an older Tektronix 2784 spectrum analyzer that I have been attempting to communicate with through GPIB. Under the NI GPIB instrument controller, when sending a *IDN?, the analyzer returns a "GPIB Syntax Error" to it's screen. I've tested the code, GPIB address and setup on other instruments and everything works fine. Could it be that the 2784 is not SCIPI compatible?

Thanks

Support for *IDN? is not part of SCPI. It is part of IEEE-488.2 and yes, it's possible that the instrument does not support the command. What does the manual say?

I don't have the manual yet, but I'm assuming that this is probably the problem.

Hello MWB,

       If you have LabVIEW, it would be worthwhile to look at the instrument driver that is on IDNet.

Thats what I'm doing now. I'm going to atleast reverse engineer the GPIB commands present in it. I'll tell you guys how it works out.
