The Virtual Instrument Software Architecture (VISA) is a standard for configuring, programming, and troubleshooting instrumentation systems comprising GPIB, VXI, PXI, Serial, Ethernet, and/or USB interfaces.
VISA provides the programming interface between the hardware and development environments such as LabVIEW, LabWindows/CVI, and Measurement Studio for Microsoft Visual Studio.
NI-VISA is the National Instruments implementation of the VISA I/O standard.
NI-VISA includes software libraries, interactive utilities such as NI Spy and the VISA Interactive Control, and configuration programs through Measurement & Automation Explorer for all your development needs.
NI-VISA is standard across the National Instruments product line. With NI-VISA, you can feel confident that your software development will not become obsolete as your instrumentation interface hardware needs evolve into the future.
