Keysight Introduces an Enhanced Electromagnetic Interference Test Receiver with Real-Time, Gapless 1 GHz Measurement Bandwidth

SANTA ROSA, Calif.--( BUSINESS WIRE )-- Keysight Technologies, Inc. (NYSE: KEYS) announced a major enhancement to its PXE Electromagnetic Interference (EMI) Receiver, extending the wideband Time-Domain Scan (TDS) with a real-time, gapless measurement capability up to 1 GHz measurement bandwidth. The new PXE Receiver enables engineers to measure from 30 MHz to 1 GHz in just one step versus the previous version that required three steps. This advancement provides high sensitivity, enables faster diagnostics, and significantly accelerates electromagnetic-compliance (EMC) and certification workflows.

Keysight's enhanced PXE EMI Receiver with Real-Time, Gapless 1 GHz Wideband Time Domain Scan triples test speed and accelerates electromagnetic compliance and workflows.

As product development cycles and the volume of new product introductions increase, EMC certification testing is rapidly becoming a bottleneck for manufacturers. Engineers are increasingly challenged by the need to identify and resolve intermittent EMI issues stemming from complex electronic designs. Keysight’s new PXE EMI Receiver directly addresses these challenges by dramatically improving test throughput, minimizing debugging time, and optimizing EMC chamber efficiency.

Benefits of the PXE EMI Receiver include:

• Faster Testing and Troubleshooting: The 1 GHz TDS bandwidth and standalone stream processing unit (N9048BSPU) speeds up measurements and cuts troubleshooting time from hours to mere minutes.
• Reliable, Real-Time Results: The 1 GHz real-time scan bandwidth ensures no transient or low-level EMI signals are missed with a gapless measurement capability.
• Regulatory Confidence: Full adherence to CISPR 16-1-1:2019 to align with the latest global EMC standards.

Yoshimichi Imaizumi, Senior Vice President of TOYO Corporation, said: “As a long-standing partner of Keysight, Toyo is proud to offer a comprehensive EMI test solution that combines the advanced capabilities of the Keysight PXE EMI Receiver with our proprietary EPX software. Together, these technologies provide a seamless, high-performance solution that enhances test automation, accelerates troubleshooting, and ensures compliance with the latest standards.”

Jason Kary, Senior Vice President and President of Keysight’s Electronic Industrial Solutions Group, said: “With the advanced PXE EMI Receiver, our customers, whether independent compliance test labs or in-house EMC teams, can now complete CISPR-compliant measurements with greater speed, confidence, and efficiency. By delivering high sensitivity, superior dynamic range, and gapless real-time monitoring, we’re empowering engineers to resolve EMI issues faster and shorten development cycles, ultimately reducing time-to-market and cost of compliance.”

Keysight’s PXE EMI Receiver sets a new standard in precision, performance, and productivity, empowering engineers and test labs to meet today’s demanding EMC challenges with confidence and speed.

The PXE EMI Receiver will be demonstrated at Techno-Frontier 2025 , July 23-25 in Tokyo at TOYO Corporation booth 3-GG04.
