Definitions for "VXI"
A newer electrical and mechanical standard (based on the VME standard, with Extensions for Instrumentation) mainly utilized in the ATE industry to assist different vendor's equipment to work together in a common control and packaging environment.
The VXI bus architecture is an open standard platform for automated test based upon VMEbus. VXI stands for VME eXtensions for Instrumentation, defining additional bus lines for timing and triggering as well as mechanical requirements and standard protocols for configuration, message-based communication, multi-chassis extension, and other features. In 2004, the 2eVME extension was added to the VXI bus specification, giving it a maximum data rate of 160 MB/s.
