The VXI bus standard was developed in 1987 by a consortium known as the VXI bus Consortium, a group of companies that includes some of the world’s largest instrument suppliers. This standard, which was based on the VME bus architecture, can be used to create portable test programs, data acquisition applications, and high-end test systems. VXI systems can be integrated with applications that test conventional GPIB instruments and switches.
The VXI bus standard has the following advantages:
Open standards to increase portability and flexibility.
Faster throughput to reduce test times.
Smaller size to reduce hardware footprint of standard rack and stack instrumentation systems.
Enhanced power and cooling specifications to simplify the addition of modules to a system.
Provides local bus for communication between devices.
