VXI

VXI (VME eXtensions for Instrumentation) is a hardware platform standard for modular electronic test and measurement systems, developed in the late 1980s. It combines the VMEbus computer architecture with instrumentation-specific extensions to create a modular, high-performance system for automated testing in industries like aerospace, defense, and telecommunications.

Also known as: VME eXtensions for Instrumentation, VXIbus, VXI Standard, IEEE 1155, VXI-11

Why learn VXI?

Developers should learn VXI when working on automated test equipment (ATE) systems, especially in environments requiring high-speed data acquisition, precise timing, and modular scalability. It is particularly useful in military, aerospace, and manufacturing applications where reliability and interoperability with legacy systems are critical.
