Time domain/time scan capabilities enhance EMI receiver

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 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 26.5GHz allows detection of small signals close to the noise level, common in radiated emissions measurements and is full compliant with CISPR 16-1-1:2015 and MIL-STD-461G (2015), ensuring devices comply with worldwide and regional standards.

TDS and accelerated TDS capabilities meet dwell measurement requirements while reducing receiver scan and test time from multiple hours to seconds.

The instrument also offers full signal visibility, where the RTS provides gapless signal capture and analysis in up to 350MHz bandwidth and simultaneously displays the frequency domain, time domain and spectrogram, with three EMC detectors.
