More About Keysight
Keysight Technologies focuses on electronic design and test workflows used in R&D labs, validation environments, manufacturing lines, and field operations. Its portfolio supports enterprises and institutions that build or operate communications infrastructure, compute systems, semiconductors, electronic subsystems, vehicles, aerospace and defense platforms, and industrial automation equipment.
In communications, Keysight provides instruments and platforms for wireless, wireline, and data center technologies (network and device testing). These offerings target protocol, RF, and system-level test for 4G, 5G, work on 6G research, Wi-Fi, and high-speed Ethernet. Enterprises and network equipment manufacturers use these solutions to validate physical layer performance, verify protocol behavior, and assess Quality of Service (QoS) across complex, multi-vendor environments. Tools span spectrum analysis, signal generation, vector network analysis, and application-specific test software integrated into automated test systems.
For electronic design, Keysight supplies software for circuit and system simulation, electromagnetic modeling, and signal analysis (design and simulation tools). Engineers apply these platforms to RF components, antennas, high-speed digital interfaces, and power electronics, linking design stages with bench and automated test. This supports workflows where design models, test plans, and measurement data are correlated, enabling design verification and regression testing under different operating conditions and standards.
In automotive and energy markets, Keysight offers test systems for electric vehicles, charging infrastructure, batteries, inverters, and vehicle networking (automotive and energy test). These systems address Power Conversion Efficiency (PCE), battery performance, on-board charger behavior, and in-vehicle communication buses. OEMs and suppliers integrate Keysight equipment into Hardware-in-the-Loop (HIL) setups and end-of-line test stands to validate components and subsystems under controlled, repeatable load profiles.
Aerospace and defense organizations use Keysight RF, microwave, and high-frequency test solutions for radar, electronic warfare, Satellite Communications (Satcom), and navigation systems (test and measurement). These environments require measurement of wideband signals, phase coherence, and dynamic range across complex waveforms and scenarios. Keysight instruments and software support analysis of modulated signals, channel effects, and compliance with relevant standards and protocols.
Across domains, Keysight’s offerings align with enterprise IT and engineering categories such as test and measurement, EDA, network performance and security testing, and specialized automotive and energy validation. The company also provides calibration, repair, consulting, and training services (professional and managed services), allowing organizations to maintain measurement traceability, optimize test strategies, and manage installed fleets of instruments across distributed sites and labs.
