Keysight Enhances PXE EMI Receiver with Real-Time, Gapless 1 GHz Measurement Bandwidth for Faster Diagnostics and EMC Certification Workflows.

Keysight has introduced an enhanced Electromagnetic Interference Test Receiver with real-time, gapless 1 GHz measurement bandwidth, enabling engineers to measure from 30 MHz to 1 GHz in one step. This advancement provides high sensitivity, faster diagnostics, and accelerates EMC and certification workflows. The new receiver helps resolve EMI issues quickly, reducing development cycles and cost of compliance.

Keysight Technologies, Inc. (NYSE: KEYS) has announced a significant 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 [1][2][3][4]. The new PXE Receiver enables engineers to measure from 30 MHz to 1 GHz in just one step, compared to the previous version that required three steps. This advancement provides high sensitivity, faster diagnostics, and significantly accelerates electromagnetic-compliance (EMC) and certification workflows.

The new PXE EMI Receiver addresses the growing challenges faced by manufacturers in EMC certification testing. As product development cycles and the volume of new product introductions increase, EMC certification testing is rapidly becoming a bottleneck. 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.

Key benefits of the PXE EMI Receiver include:

- Faster Testing and Troubleshooting: The 1 GHz TDS bandwidth and standalone stream processing unit (N9048BSPU) significantly 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 aligns with the latest global EMC standards [1][2][3][4].

Yoshimichi Imaizumi, Senior Vice President of TOYO Corporation, highlighted the benefits of the new PXE EMI Receiver, stating, “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” [1][2][3][4].

Jason Kary, Senior Vice President and President of Keysight’s Electronic Industrial Solutions Group, noted, “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” [1][2][3][4].

The PXE EMI Receiver will be demonstrated at Techno-Frontier 2025, July 23-25 in Tokyo at TOYO Corporation booth 3-GG04 [1][2][3][4].
