An instrument driver is a set of VIs that communicate with an instrument using LabVIEW's standard VISA I/O functions. Each VI corresponds to a programmatic operation, such as configuring, reading from, writing to, and triggering an instrument. LabVIEW instrument drivers eliminate the need to learn the complex, low-level programming commands for each instrument.
The LabVIEW instrument driver library contains instrument drivers for a variety of programmable instruments that use the GPIB, VXI, or serial interfaces. You can use a library driver for your instrument as is. However, instrument drivers are distributed with their block diagram source code, so you can customize them for your specific application if need be.
Refer to the National Instruments Web site for information about acquiring instrument drivers.
If an instrument driver for your particular instrument does not exist, you can:
