NI-VISA is the National Instruments implementation of the VISA I/O standard. It provides the programming interface between hardware and application development environments such as NI LabVIEW, LabWindows™/CVI, and Measurement Studio for Microsoft Visual Studio.
NI-VISA development licenses are included with National Instruments products such as development environments and GPIB hardware. NI-VISA run-time deployment licenses are included on deployed systems that feature NI hardware, NI development environments, and applications written using NI development environments.
