I have a ol

d 4195A HP spectrum/network analyzer. Do I need an instrument driver (I cant find one)? I can send it commands to retrieve data. So can I just use this data to simulate the screen that's on the network analyzer? I need to grab the screen from the analyzer.

No you dont need an instrument driver. You could place the GPIB/GPIB 488.2 or VISA library direct in your code. They is an example in the CVI Samples under I/O Interfaces | GPIB or VISA.

Good Luck

I need to grab the screen from the analyzer.You could find a driver for this instrument at http://www.ni.com/devzone/idnet/default.htm . If it's not listed there, it leaves you with one of a couple options. First, I would like you to submit a request for this driver at: http://zone.ni.com/idnet97.nsf/instrumentdriverrequest/
We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
http://www.ni.com/devzone/idnet/development.htm
We also have a syndicate of third party vendors that specialize in National Instruments' products and services. Some
of the vendors specialize in driver development. I would suggest contacting one of the Alliance members at:
http://www.ni.com/alliance

There are example VI's in CVI on Instrument Connectivity, C:\Program Files\National Instruments\MeasurementStudio\CVI\samples. I would suggest tweaking them to suit your application. Also the specific command that your instrument responds to can be found from it's manual.

Some useful resources for your application are
ni.com > NI Developer Zone > Development Library > Instrument Connectivity
