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, Keysight Technologies
(formerly Agilent Technologies) 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 2600 products in over 50 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.
