Hi Karin,

What do you have for development tools?

LabVIEW or Visual Basic would be the easiest way to go

Hi Curt

I have LabVIEW.

Best,

Karin.

Can I get a hint to how to do this in LabVIEW? I must admit that I haven't worked with it before.

Best,

Karin.

Basicqlly each of the OUTPUT statements would be a VISA Write function and the ENTER is a VISA Read. The output of the VISA Read is a string that would be need to be converted but how would depend on the type of data you are reading (i.e. wavefolrm array, scalar, etc.). I would suggest the basic LabVIEW tutorial.

Hi Karin,

You should be able to find a sample gpib VI at

C:\Program Files\National Instruments\LabVIEW #.#\examples\instr\smplgpib.llb\LabVIEW - GPIB.vi 

Good luck with your task

Curt

it is quite simple: you need first to open the communication with the module in the OSA, not with the OSA itself.

Then it is just a matter of WRITE and READ commands.

In the attached vi I acquire the spectrum, and decided which scale (linear or dB) to use.
