Yes you can connect a PC to your instrument via GPIB.
Some useful resources for your application are
ni.com > NI Developer Zone > Development Library > Instrument Connectivity
http://search.ni.com/?col=alldocs&layout=TechResources&ql=a , to search examples and knowledge bases
There are example VI's in LabVIEW on Instrument Connectivity. If you go to the Help menu >> Examples.. >> I/O, you will see a couple.
You could find a LV/CVI 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:

Hope this helps.
