Test and measurement equipment company; also develops EDA tools.


Keysight Technologies is a test and measurement equipment company. It develops advanced design and validation solutions that span the development lifecycle, including design simulation, prototype validation, automated software testing, manufacturing analysis and network performance optimization and visibility in enterprise, service provider and cloud environments. Customers span worldwide communications and industrial ecosystems, aerospace and defense, automotive, energy, semiconductor, and general electronics markets. The company generated $4.9 billion revenue for fiscal 2021.

Some products include EDA tools, oscilloscopes, analyzers, meters, emulators, signal generators, wireless emulators and analyzers, in-circuit test systems, and more.

Keysight’s history goes back to Hewlett-Packard, which began making oscilloscopes in 1938 and expanded to spectrum analyzers and other test and measurement equipment through the following decades.

In 1999, HP spun out Agilent Technologies, consisting of HP’s former measurement, components, chemical analysis, and medical businesses. HP retained its computer and printer businesses. The new company listed on the New York Stock Exchange.

In August 2014, Agilent spun out its electronic measurement segment, creating Keysight Technologies. Agilent remained focused on chemical analysis and life sciences. Keysight (KEYS) listed on NYSE in November 2014.
