LabVIEW Instrument Modules are prebuilt drivers, VIs, and function libraries that enable communication, control, and automation of laboratory and industrial instruments using National Instruments LabVIEW. They provide ready-to-use interfaces for instruments connected via GPIB, USB, Serial, Ethernet, PXI, or modular hardware.
Primary Use Cases
- ▸Controlling oscilloscopes, multimeters, power supplies
- ▸Automated test sequences for manufacturing
- ▸High-speed data acquisition using PXI hardware
- ▸Remote instrument monitoring over TCP/IP
- ▸Synchronized multi-instrument test automation
Notable Features
- ▸Extensive instrument driver library (over 10,000 devices)
- ▸Native SCPI command wrappers
- ▸Plug-and-play front-panel interfaces
- ▸Built-in VISA and DAQmx integration
- ▸Support for modular PXI/PXIe hardware
Origin & Creator
Developed by National Instruments (NI) as part of the LabVIEW ecosystem.
Industrial Note
Instrument modules are essential in ATE (Automated Test Equipment) systems, where consistent device communication across multiple vendors is required for deterministic measurements.
