Using LabVIEW with IVI Instrument Drivers

In addition to the more than 700 LabVIEW source code drivers, you can control instruments with Interchangable Virtual Instruments (IVI) instrument drivers. IVI instrument drivers are DLL-based drivers developed in LabWindows/CVI that give production test users additional benefits, including the following:

IVI drivers in LabVIEW are created from code-linked CVI IVI drivers.

The Import CVI Instrument Driver utility creates an .rc file for each imported CVI IVI driver. LabVIEW expects all .rc files to be in the instr.lib directory. Place all CVI IVI instrument drivers in the instr.lib directory before import them using this utility.

IVI properties can be accessed through the Property Node. Refer to VISA Properties for information about how the Property Node works.
