Keysight adds time domain and real time scan to EMI receiver

Keysight Technologies announces the addition of time domain scan (TDS) and real time scan (RTS) capabilities to the Keysight N9048B PXE electromagnetic interference (EMI) receiver. This, says the company, enables real time measurements and diagnostics for faster electromagnetic compliance (EMC) certification.

EMC testing requires detailed and exacting methodologies to accurately measure all emissions. To have lengthy test times can restrict the availability of a test facility and reduce the number of devices that can be certified.

Keysight also points out that it is easy to miss intermittent disturbance signals with conventional scan mode since long dwell time is required at each frequency.

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 simplifies and reduces the time needed for test efforts of global EMC test labs, explains Keysight.

The N9048B PXE EMI receiver, with three frequency ranges up to 26.5GHz, delivers what is claimed to be industry leading sensitivity performance which allows detection of small signals close to the noise level, common in radiated emissions measurements. It also complies 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 many hours to seconds.

The N9048B PXE EMI receiver also provides 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.
