Keysight Technologies, Inc. is a global company headquartered in Santa Rosa, California, that manufactures hardware and software for engineering workflows across design, test, and emulation. It serves industries including 5G communications, aerospace and defense, automotive, semiconductors, digital healthcare, and energy.
The company was formed as a spin-off of Agilent Technologies, which inherited and rebranded the test and measurement product lines developed and produced, from the late 1930s to the turn of the millennium, by Hewlett-Packard. Its name is a combination of key- and -sight.
Satish Dhanasekaran took over as Keysight's CEO in 2022. Some other executives at Keysight Technologies include CTO Jay Alexander, CIO Daniel Krantz, CMO Marie Hattar, CSCOO Ingrid Estrada, CFO Neil Dougherty, and Corporate Controller Lisa Poole. The Chief People Officer (CPO) at Keysight is Jodi Juskie.
Through expansions and acquisitions, the S&P 500-indexed company has grown beyond its initial focus on oscilloscopes to produce electronic design automation (EDA) software, network visibility and cybersecurity solutions, manufacturing technology, and system-level simulation platforms.
Keysight works closely with more than 35 international engineering standards bodies to develop new standards and ensure accurate tests.

History
Acquisitions In the same year of its spin-off from Agilent (2014), Keysight expanded its multi-vendor calibration offerings by finalizing the acquisition of Primary Standards North America. Keysight acquired British electronic measurement instrument maker Anite in 2015 for £388 million ($607 million). It also purchased U.K.-based calibration company Electroservices Enterprises the same year. In 2016, it acquired Signadyne, a quantum-focused modular measuring equipment company incubated by the ICFO (Institute of Photonic Sciences).
In 2017, Keysight acquired data technology company Ixia, including its network security solution BreakingPoint, for about $US1.6 billion in cash. It acquired Scienlab electronic systems GmbH, including its China division, in 2017 for $62 million. Expanding its calibrations services even further, the company acquired Liberty Calibration in 2017 and Melbourne-based Thales Calibration Services in 2018. Additionally, Keysight acquired Prisma Telecom Testing Srl in 2019 for $90 million.
The company acquired British software testing company Eggplant Software from The Carlyle Group for $330 million in 2020. In March of that year, it also acquired quantum computing instrument control and lab automation software company, Labber.
From 2019 to 2021, the company focused on 5G, introducing advanced products such as the Infiniium UXR-Series oscilloscopes. It acquired California-based Scalable Network Technologies in 2021 to expand its software and digital twin capabilities. The same year, Keysight also acquired Sanjole, a Hawaiian technology firm focused on testing wireless data networks, German EV charging test company Verisco GmbH, as well as quantum computing testing company Quantum Benchmark.
Keysight invested in quantum, high-speed digital/6G, and software-defined vehicle tech, respectively, in 2022 with acquisitions of QuaMotion, Micram Microelectronic GmbH, and NORDSYS.
In 2023, the company acquired France-based ESI Group for approximately $1 billion, as well as Cliosoft, Inc., data property management platform, for $85 million.
Keysight outbid Viavi Solutions in 2024 to acquire British telecommunications testing company Spirent for $1.5 billion. That June, the US Department of Justice required the company to divest three of Spirent's businesses prior to closing the sale, due to antitrust concerns. The sale closed October 15, 2025, including the regulatory required spin-off of three divisions.
Keysight acquired multiple other companies in 2024, including AnaPico, a Swiss RF and microwave test and measurement company, for $117 million. It also acquired Riscure, automated device and semiconductor security company, for $78 million, and Easics, a Belgian ASIC chip design services company.
Keysight acquired Synopsys Optical Solutions Group, an optical design and analysis software platform, from Synopsys, Inc., and PowerArtist, an RTL (Register-transfer level) power consumption analysis tool, from Ansys, Inc., in 2025. The Synopsys Optical Solutions Group acquisition expanded Keysight's capabilities in imaging systems design, illumination design, and automotive lighting design, plus virtual prototyping and electromagnetic photonic and optoelectronic simulation. PowerArtist expanded Keysight's role in semiconductor design with early-stage power analysis.
Controversies On August 3, 2021, Keysight entered into a consent agreement with the Directorate of Defense Trade Controls, Bureau of Political-Military Affairs, Department of State ("DTCC") to resolve alleged violations of the Arms Export Control Act and the International Traffic in Arms Regulations ("ITAR"), after agreeing to a $6.6 million fine. On May 3, 2024, Keysight submitted a letter to the DTCC certifying that it had implemented all aspects of the consent agreement and that the company's compliance program was adequate to identify, prevent, detect, correct, and report violations of the ITAR.
In its 2024 Corporate Social Responsibility Progress Report, Keysight claimed successful completion of the consent agreement and the formal closure of the matter with the DTCC. It continues to provide ITAR data handling support for its customers with EDA (electronic design automation) support agreements.
Research and development From its launch in 2014 until 2020, Keysight increased its investment in R&D from approximately 12% to 16%, a percentage increase that represented almost a doubling of the investment in absolute dollars. In 2025, Keysight's research and development expenses reached $1.007B, a 9.58% increase over the previous year ($919M in 2024). Keysight's research and development budget has consistently increased annually since its 2014 spin-off from Agilent Technologies. Its current focus is on enabling technologies, system design, simulation, and measurement, with R&D distributed throughout the US, Singapore, India, Germany, Malaysia, Romania, China, Japan, Spain, United Kingdom, and France.
In 2024, Keysight collaborated with Google Quantum AI to introduce the industry's first quantum circuit simulation with flux quantization, representing a breakthrough in quantum computing and superconducting circuit design. This was followed in 2025 by Keysight's delivery of a quantum control system to the National Institute of Advanced Industrial Science and Technology (AIST) in Japan capable of supporting over 1,000 qubits, as part of the organizations’ ongoing quantum research.
Keysight focuses R&D efforts on AI data center infrastructure and networking technologies, including a 2025 survey report conducted by Heavy Reading on the infrastructure challenges facing AI advancements. Keysight collaborated with McGill University, Ciena, and Hyperlight on the industry's first demonstration of 448G PAM4 driverless optical transmission in 2025, which was also demonstrated at the European Exhibition on Optical Communications (ECOC) [link] and through collaboration with NTT Innovative Devices and Lumentum at an Optical Fiber Communications Conference (OFC) demonstration the same year.
Keysight is also advancing research in non-terrestrial networks (NTN) that integrate satellite and terrestrial communications for future 5G and 6G communications. In 2026, Keysight collaborated with Airbus UpNext on the SpaceRAN demonstrator to validate 5G NTN capabilities using software-defined satellite technology. The company also works with Samsung Electronics to validate new NR-NTN devices using its 5G Network Emulator, supporting satellite-to-mobile connectivity aligned with emerging low-Earth-orbit (LEO) constellations such as Starlink.
Recognition Keysight won the 2014 Global Frost & Sullivan award for market leadership with $300 million in instrumentation software revenue, with its R&D investment of 12% of revenue ($365 million in 2013) cited as an important factor.
In 2022, Keysight was ranked No. 46th on Fortunes 100 Best Companies to Work For list.n 2023, Keysight was recognized by Forbes as #5 of America's Best Midsize Employers and #123 of America's Most Cybersecure Companies.
