what is Gpib handle number ?

Hi,

The GPIB handle number is usually the reference returned by the Initialisation function (OpenDev() - for NI488, viOpen - for VISA), which you pass to all the other functions.

I dont recognise that panel, where does that come from?

I'm using the GPIBSteps which provided from NI,

usually I guess the "handly number" is specify the instruments gpib address, even then that lot of instruments have theirs different instruments address to control.

Hi,

It is as I said in my initial reply. Its the handle returned by the open function. You supply the board index, primary address and second address and a variable to hold the return value eg. Locals.MyInstrumentHandle.

You then use this variable in the other GPIB Steps such as the GPIB write and GPIB read.

Have you looked at the readme file which is part of the zip file you attached.
