Time-Domain and Real-Time Scan Capabilities in EMI Receiver Solution

Keysight Technologies, Inc. announced the addition of Time Domain Scan (TDS) and Real Time Scan (RTS) capabilities to the Keysight N9048B PXE Electromagnetic Interference (EMI) receiver, which is fully compliant with CISPR 16-1-1 and MIL-STD-461 standards, and enables real time measurements and diagnostics for faster electromagnetic compliance (EMC) certification.

EMC testing requires detailed and exacting methodologies to ensure that all emissions are accurately measured. Long test times impact test facility availability and reduce the number of devices that can be certified. It’s also easy to miss intermittent disturbance signals with conventional scan mode since long dwell time is required at each frequency. Keysight’s new TDS and RTS capabilities in the N9048B PXE EMI receiver enable independent compliance test laboratories, as well as in-house self-certification labs, to shorten overall test time and easily perform gapless signal capture and analysis, certifying that a product meets regulatory compliance standards.

“The introduction of Keysight’s new scan capabilities simplifies and exponentially reduces the time needed for test efforts of global EMC test labs,” said Joe Rickert, vice president and general manager of high frequency measurement R&D for Keysight’s communications solutions group. “With guaranteed compliance to the EMC standards, leading performance, and EMC focused application software, certification labs can confidently handle any new product that requires compliance testing – in a fraction of the time versus other solutions.”

The N9048B PXE EMI receiver, with three frequency ranges up to 26.5 GHz, delivers:

Industry leading sensitivity performance which allows detection of small signals close to the noise level, common in radiated emissions measurements
Full compliance with CISPR 16-1-1:2015 and MIL-STD-461G (2015), ensuring devices comply with worldwide and regional standards
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 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
