History of LXI

Looking at the evolution of test busses, in 1972 Hewlett-Packard engineers invented the Hewlett-Packard Interface Bus (HP-IB) as an open standard communications bus (IEEE-488) from instruments to the computer. For almost 40 years, GPIB instruments (also known as rack-and-stack instruments) were the preferred architecture for test systems.

In 2005, Agilent Technologies (formerly Hewlett-Packard) and VXI Technology, Inc. (Now VTI) introduced LXI; combining the best of GPIB instruments and VXI and PXI modules, LXI provides the high throughput of LAN, The global recognition that GPIB has, as well as test related features pioneered in VXI & PXI.

With over 55 of the top T&M companies sponsoring and developing this technology, and more than 1740 products in over 220 different product families, LXI (LAN eXtensions for Instrumentation) is the current and future standard for T&M. It's seen the fastest ramp-up of any communications standard in the history of the test industry and products from leading test and measurement companies. Click to view LXI Growth.
