The EMI receiver upgrade lets engineers test signals in one step, helping them find issues and speed up product testing and approval.
Keysight Technologies, Inc. has announced a major upgrade to its PXE Electromagnetic Interference (EMI) Receiver, introducing real-time, gapless measurement across a 1 GHz bandwidth. This allows engineers to measure signals from 30 MHz to 1 GHz in a single step instead of the previous three-step process, resulting in higher sensitivity, faster diagnostics, and quicker electromagnetic compliance (EMC) and certification workflows.
As EMC certification becomes a growing bottleneck in product development—driven by shorter timelines and more product launches—engineers face increasing challenges in identifying and resolving intermittent EMI issues caused by complex electronics. The enhanced PXE EMI Receiver directly addresses these issues by improving test throughput, reducing debugging time, and increasing the efficiency of EMC testing chambers.
The system uses a 1 GHz Time Domain Scan (TDS) bandwidth along with a dedicated stream processing unit (N9048BSPU) to deliver faster testing and troubleshooting. This combination cuts measurement time significantly, reducing what used to take hours down to just minutes.
It also ensures reliable, real-time results. The 1 GHz real-time scan bandwidth enables continuous, gapless measurements, making sure that no transient or low-level EMI signals are missed during testing.
In addition, the PXE EMI Receiver supports full compliance with CISPR 16-1-1:2019, aligning with the latest global EMC standards and offering users confidence in regulatory testing. Keysight claims the receiver sets a new benchmark in precision, performance, and efficiency, helping engineers and test labs meet complex EMC challenges with greater speed and assurance.
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.”
