What is a VI file?
Program created with LabVIEW, a scientific testing and measurement application; referred to as a "virtual instrument" because it imitates the appearance and operation of a physical instrument, such as a multimeter or oscilloscope.
Virtual instruments can be created from scratch or built from a VI template included with the LabVIEW software.
