The Virtual Instrument Software Architecture (VISA) is a standard for configuring, programming, and troubleshooting instrumentation systems comprising GPIB, VXI, PXI, serial (RS232/485), Ethernet, USB and/or IEEE 1394 interfaces. VISA provides the programming interface between the hardware and application development environments such as NI 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 for all your development needs. NI-VISA is standard across the National Instruments product line. With NI-VISA, you can remain confident that your software development will not become obsolete as your instrumentation interface hardware needs evolve into the future.
