Keysight unveils probes for high-voltage device testing

SANTA ROSA, Calif. - Keysight Technologies, Inc. (NYSE: KEYS), a $26.4 billion market cap technology leader with robust financials including a healthy 2.95 current ratio, has announced the launch of a new family of optically isolated differential probes designed to improve testing efficiency and performance for high-voltage, fast-switching semiconductors. The probes, which offer significantly enhanced common-mode rejection capabilities, will be showcased at the upcoming Applied Power Electronics Conference (APEC) 2025. According to InvestingPro, nine analysts have recently revised their earnings expectations upward for the upcoming period, suggesting strong confidence in the company’s growth trajectory.

The new isolated differential probes are engineered to provide accurate and safe measurements in environments with high common-mode voltages and noise levels. They are particularly suited for testing devices such as wide bandgap GaN (Gallium Nitride) and SiC (Silicon Carbide) semiconductors, which are prevalent in power conversion, motor drives, and inverters. With a strong gross profit margin of 62.6% and annual revenue of $5 billion, Keysight maintains a leading position in the test and measurement market.

Keysight’s technology stands out by offering up to 100 dB greater common-mode rejection compared to standard differential probes. This level of performance is crucial for engineers working with floating circuits in high-voltage applications, where accurate measurement of small differential signals is often obstructed by noise interference and safety concerns.

The probes boast up to 1 GHz bandwidth and a differential voltage range of ±2,500 V, enabling detailed analysis of the fast-switching behavior of GaN and SiC devices. This capability is expected to drive advancements in efficiency and switching loss testing across various high-voltage applications, including electric vehicles, solar energy systems, battery management, and more.

Robert Saponas, Vice President and General Manager at Keysight, highlighted the company’s commitment to innovation in power integrated circuits, emphasizing the importance of providing customers with top-tier power testing technology for their forthcoming breakthroughs.

The announcement of these isolated differential probes expands Keysight’s suite of power solutions, which aims to streamline workflows for power integrity, supply, and efficiency testing. Interested parties can visit booth #829 at APEC for a closer look at the new probing technology and other Keysight solutions.

This development is part of Keysight’s ongoing efforts to empower innovators in various industries, from communications and industrial automation to aerospace, defense, and automotive, by providing advanced design, emulation, and test solutions throughout the product life cycle.

In other recent news, Keysight Technologies has announced a collaboration with Capgemini to accelerate the development of 5G New Radio Non-Terrestrial Networks. This partnership aims to enhance global connectivity by integrating Capgemini’s 5G NR NTN ready Radio Access Network framework. In another development, Keysight has been selected by the U.S. Army to employ its CyPerf solution to validate the Unified Network Program’s performance and security. This initiative is part of the Army’s effort to integrate tactical and enterprise systems into a unified network. Additionally, Keysight is collaborating with Samsung and NVIDIA to improve radio access network performance using AI models, focusing on enhancing system capacity and reducing power consumption.

Meanwhile, Deutsche Bank has revised the price target for Spirent Communications to GBP2.01, down from GBP2.50, while maintaining a Buy rating. This adjustment follows Spirent’s agreement to sell its high-speed Ethernet testing business to Viavi Solutions, a move that is expected to facilitate Keysight’s acquisition of Spirent. The transaction is projected to conclude by April 30, 2025. Viavi has announced plans to acquire Spirent’s high-speed ethernet and network security business lines from Keysight for $425 million, with the deal expected to close in the second quarter of 2025. This acquisition is anticipated to contribute approximately $180 million to Viavi’s revenue in the first year post-closing and to be accretive to earnings per share.
