Keysight Technologies (NYSE: KEYS) is an electronic measurement and test equipment company that designs, manufactures, and sells hardware instruments, software, and services used to develop, validate, and optimize electronic systems. Revenue comes from selling standalone instruments, software licenses, software application solutions, and associated services, with products delivered on a transactional basis or bundled into application-specific solutions. Keysight serves approximately 40,000 end customers annually, including many Fortune 1000 companies, across commercial communications, aerospace and defense, automotive, semiconductor, and general electronics markets. The company generated $5.4 billion in revenue in FY2025 (fiscal year ended October 31, 2025), up from $5.0 billion in FY2024 and $5.5 billion in FY2023. Net income was $850 million in FY2025. The company traces its heritage more than 80 years to Silicon Valley and operates R&D centers across the United States, Germany, Singapore, India, Malaysia, Japan, China, and several other countries.

Revenue model

Keysight earns revenue through sales of hardware instruments (spectrum analyzers, network analyzers, signal generators, oscilloscopes, and modular platforms), standalone software solutions (design simulation, test automation, quality assurance), instrument software applications, and services. Products are sold directly through a dedicated sales and solution engineering force and through distribution channels. Revenue is primarily transactional, with software licenses and services providing recurring components.

Products and services

Hardware products include spectrum and signal analyzers, network analyzers, signal generators, oscilloscopes, and modular instruments across radio frequency, microwave, and optical frequency ranges. Software offerings include instrument software applications, software application solutions that unify multiple instruments, and standalone software for design simulation, emulation, test automation, computer-aided engineering, and quality assurance. Services include calibration, repair, and professional services. Solutions are often delivered as integrated hardware-software packages targeting specific applications such as 5G validation, satellite communications testing, and cybersecurity testing.

Customers and end markets

Keysight serves approximately 40,000 end customers annually as of FY2025, including original equipment manufacturers, contract manufacturers, network equipment manufacturers, communications network service providers, cloud computing providers, semiconductor companies, aerospace and defense prime contractors, government defense and security agencies, and automotive and energy companies. Key demand drivers include R&D investment in 5G evolution, early 6G development, high-speed data center networks, satellite networks, and defense system modernization.

Value-chain role

Keysight occupies the design, simulation, validation, and manufacturing test phase of the electronics value chain. Customers use Keysight instruments and software upstream of production to characterize components, validate designs, ensure standards conformance, and optimize deployed systems. This positions Keysight as a supplier to R&D labs and manufacturing quality assurance functions rather than a component or end-product maker.

Geographic exposure

Keysight operates globally with R&D centers in the United States (California, Colorado, Texas), Germany, Singapore, India, Malaysia, Romania, China, Japan, Spain, United Kingdom, and France. The company conducts business with customers worldwide, including commercial and government customers across North America, Europe, and Asia-Pacific, though specific regional revenue splits are not detailed in the excerpts reviewed.
