Keysight Technologies, or Keysight, is a US company that manufactures electronics test and measurement equipment and software. In 2014, Keysight was spun off from Agilent Technologies, taking with it the product lines focused on electronics and radio, leaving Agilent with the chemical and bio-analytical products.[4]

The name is a blend of key and insight, and was chosen to convey that the company "unlocks" "critical or key insights."[2][5]


Keysight's products include hardware and software for benchtop, modular, and field instruments.[6] Instruments include oscilloscopes, multimeters, logic analyzers, signal generators, spectrum analyzers, vector network analyzers, atomic force microscopes (AFM), automated optical inspection, automated X-ray inspection (5DX), in-circuit testers, power supplies and handheld tools.[7] In addition, it produces electronic design automation (EDA) software (EEsof division).[8] It mainly serves the telecommunications, aerospace/defense, industrial, computer, and semiconductor industries.[9]


Prior to its existence as an independent company, the group that became Keysight was the electronic test and measurement division of first Hewlett-Packard, and later Agilent. HP began as a company making electronic test equipment, with the computer and life sciences products coming later. In 1999, HP spun-off all test and measurement products into Agilent and retained the computer and printer businesses.[10] On November 1, 2014, the formal separation of Agilent and Keysight Technologies was completed, with Agilent retaining the life science businesses. The separation was implemented through a spinoff of Keysight’s common stock. Agilent shareholders received one share of Keysight common stock for every two shares of Agilent common stock held October 22, 2014.

In June 2015, Keysight announced it would acquire the UK’s Anite PLC in a deal worth £388 million.[11]

In August 2015, Keysight announced the acquisition of the UK’s Electroservices Enterprises UK Ltd comprising Electroservices (Midlands) Ltd. and Micro Movements Ltd.[12] Micro Movements Ltd., a bespoke electronic measurement solutions business, was originally incorporated in 1994, with expertise in measurement solutions across a broad range of industry sectors. The company was incorporated into Electroservices Enterprises UK Ltd in 2013.

In 2017, Keysight acquired Ixia for about $1.6 billion in cash.[13][14][15]

In October 2017, its headquarters sustained some damage in the Tubbs Fire.[16][17][18]


Keysight won the 2014 Global Frost & Sullivan award for market leadership with $300 million in instrumentation software revenue. The citation states R&D investment of 12% of revenue ($365 million in 2013) as an important factor.[19]
