Validation of floating half-bridge and full-bridge architectures commonly used in power conversion, motor drives, and inverters requires measurement of small differential signals riding on high common-mode voltages. This measurement can be challenging due to voltage source fluctuations relative to ground, noise interference, and safety concerns. Isolated differential probes are galvanically isolated and reject common-mode voltages, enabling power electronics engineers to measure floating circuits accurately and safely in high-voltage, noisy environments. This technology will drive progress in efficiency and switching loss testing for high-voltage applications like electric vehicles (EVs), solar energy, battery management systems, and more.
Keysight’s isolated differential probes provide up to 10 billion times greater common-mode rejection than standard differential probes, making them ideal for high-voltage, high-side measurements. With up to 1 GHz bandwidth and a ±2,500 V differential voltage range, these probes enable accurate analysis of fast-switching GaN and SiC devices.
Robert Saponas, Vice President and General Manager of Keysight’s Digital and Photonics Center of Excellence, said: “Keysight recognizes the future of power integrated circuits going beyond Moore’s law, and we are committed to equipping our customers with the best power testing technology for their next breakthrough. Introducing Keysight’s isolated probes expands our suite of power solutions that streamline our customer's power integrity, supply, and efficiency testing workflow.”
