I see that scope has been discontinued by tek. I am not that familiar with the specific instrument, but I don't see any big problem that would prevent NI-VISA from recognizing the scope and working with it.
I don't actually know what kind of physical interface the instrument offers for connectivity with PCs. Is it an ethernet port or USB? Since you were talking about a "Virtual GPIB" resource, I guess the tek must have something different from a GPIB port to connect to.
- browse to the <a href="http://www.ni.com/drivers" target="_blank">www.ni.com/drivers</a> page, click on the Download button to the left and search for a suitable driver for your instrument
- browse the tek web page and see if they still offer an instrument driver for that instrument. If it is IVI compliant (look <a href="http://www.tek.com/site/sw/detail/1,1059,3482,00.html" target="_blank">http://www.tek.com/site/sw/detail/1,1059,3482,00.html</a>) then it is likely to have a .fp file in the driver. The .fp file is a library file that can be used directly in CVI or imported in LabVIEW (Tools>>Instrumentation>>Import CVI Instrument Driver).
- you reported a specific resource that appears to be GPIB8::1::INSTR. This is already a VISA resource. So from LabVIEW, when browsing for VISA resources, you should see this.
