gpib initialization

[fatoni]

Dear all,

I am a beginner in LabVIEW, especially on how to control my instrument (vector network analyzer, HP8714C) using GPIB/USB interface (Agilent 82357B). I can get the information about GPIB interface on MAX, but I have an EVDR error when I run the LabVIEW<->GPIB.vi.  I try to initialize this GPIB using GPIB initialization function, is this step correct? When I run this VI I found error again. I don't know what type of error is. I have given input to the GPIB initializaion according to data from MAX.

How can I solve this problem? Thak you.

It sounds like you're trying to use the lower-level GPIB functions. You should not need to do this. You should, instead, try to use VISA. Is the 8714C just a different frequency version of the 8714B? If so, you can try the drivers that are available on IDNET.

In fact, you have to use VISA. The low level GPIB functions are for NI cards only.

Good point, Dennis. My eyes scanned the message so fast they missed the model of the card that was being used.
