VCIbus hardware. VME eXtensions for instrumentation bus (VXI bus) refers to standards for automated test based upon VMEbus.VXI defines 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.
There are also some specifications for T&M-specific protocols over PC-standard I/O, such as HiSLIP [2] or VXI-11 [3] (over TCP/IP) and USBTMC [4] (over USB). The VISA library has standardized the presentation of its operations over several software reuse mechanisms, including through a C API exposed from Windows DLL , visa32.dll, over the ...
The VXI bus architecture is an open standard platform for automated test based on the VMEbus. Introduced in 1987, VXI uses all Eurocard form factors and adds trigger lines, a local bus, and other functions suited for measurement applications.
The VXIplug&play Systems Alliance was founded in 1993 [2] with the aim of unifying VXI hardware and software to achieve 'plug and play' interoperability for VXI and GPIB instruments. As part of the unifying process, VXIplug&play instrument drivers [3] were also defined.

The current VME64 includes a full 64-bit bus in 6U-sized cards and 32-bit in 3U cards. The VME64 protocol has a typical performance of 40 MB /s. [ 3 ] Other associated standards have added hot-swapping ( plug-and-play ) in VME64x , smaller 'IP' cards that plug into a single VMEbus card, and various interconnect standards for linking VME systems ...
It was specified by the IVI Foundation [1] and is intended to replace the older VXI-11 [2] protocol. Like VXI-11, HiSLIP is normally used via a library that implements the VISA API. Version 1.4 of the LAN eXtensions for Instrumentation (LXI) standard recommends HiSLIP as “LXI HiSLIP Extended Function for LXI based instrumentation”.
PCI eXtensions for Instrumentation (PXI) is a modular instrumentation platform originally introduced in 1997 by National Instruments.PXI is promoted by the 69-member PXI Systems Alliance (PXISA), whose sponsor members are (in alphabetical order) ADLINK, Cobham Wireless, Keysight Technologies, Marvin Test Solutions, National Instruments, Pickering Interfaces and Teradyne.
