The VXIbus Overview
Prior to 1987 there existed only one major architecture standard for instruments...the General Purpose Interface Bus (GPIB). Although the GPIB was widely used, it did not address the need for portable test stations, nor for the market demand for faster, more cost-effective test solutions. In 1987, The VXIbus Consortium, a consortium of test and measurement companies introduced VXIbus ... a standard instrument architecture utilizing a modular platform.
The VXIbus (VMEbus eXtensions for Instrumentation) was developed to meet the need for portable applications and to provide a standard modular open architecture for integrating into the traditional GPIB test system and for stand-alone applications. It was designed to be an open architecture standard for instruments on a card, allowing an instrument from any manufacturer to operate in the same mainframe as another manufacturer’s instrument.

VXI 4.0: How can I benefit?
How your application can profit from this new specification
By Dr. Fred Blönnigen, CEO of Bustec
With so many new and successful bus structures like LXI and PXIe, the question ”What value does VXI rev. 4.0 present?” is a valid one. We will take this opportunity to show the user the benefits of the new specification VXI 4.0. First of all, we should mention that VXI 4.0 is fully backward compatible. System developers who have adopted the VXIbus platform can preserve initial development efforts and more importantly can keep all previous investments, while integrating emerging technology into their test systems. Longevity is the main interest for system integrators who have to support their systems with long lifecycles like in military test systems. Systems designed in the early days of VXI are still fully supported today and can be extended without changing any of the existing infrastructures.
