Virtual instrument software architecture
Virtual instrument software architecture (VISA) is a widely used
.The VISA standard).
The VISA library has standardized the presentation of its operations over several software reuse mechanisms, including through a C API exposed from Windows
DLL, visa32.dll, over the Microsoft COM technology, and through a .NET API. Although there are several VISA vendors and implementations, applications written against VISA are (nominally) vendor-interchangeable thanks to the standardization of VISA's presentation and operations/capabilities. Implementations from specific vendors [specify] are also available for less common programming languages [specify
] and software reuse technologies.
History
VISA was originally standardized through the VXIplug&play Alliance, a now-defunct T&M standards body. The current standard, "VISA Specification 5.0", is maintained by the IVI Foundation.
