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 and 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.
