Keysight Technologies, Inc., has extended the company's N9048B PXE Electromagnetic Interference (EMI) Receiver from 26.5 to 44 GHz enabling customers to meet current and emerging compliance testing requirements according to various standards bodies, including MIL-STD-461G and FCC Part 15.

The cellular (5G) and automotive industries need to leverage higher frequencies to deliver new applications requiring increased spectrum resources to carry large amounts of data at faster speeds. These higher frequency applications must meet electromagnetic compatibility (EMC) compliance testing and commercial application requirements before they can be brought to market. EMI receivers measure unwanted emissions at high frequencies generated by a device under test (DUT).

Keysight's PXE is a standards-compliant EMI receiver and diagnostic signal analyzer that supports a frequency range of 2 Hz – 44 GHz. Key features include:

• Sensitivity performance that allows detection of small signals close to the noise level, common in EMC compliant radiated emissions measurements, enabling customers to identify emissions caused by their device.
• Full compliance with CISPR 16-1-1:2019 and MIL-STD-461G (2015).
• Time domain scan (TDS) and accelerated TDS capabilities to meet dwell measurement requirements while reducing receiver scan and test time from multiple hours to seconds.

Full signal visibility, where the real time scan (RTS) provides gapless signal capture and analysis in up to 350 MHz bandwidth and simultaneously displays the frequency domain, time domain and spectrogram, with three EMC detectors.
