CERTIFICATION


Real-time scanning boosts certification speed


EMI receiver improves EMC certification performance for test houses with the introduction of time domain and real time scanning capabilities.


R


eacting to industry requirements for greater levels of EMC certification whilst minimising product development times, RFI and EMC testing specialist Keysight Technologies, has added Time Domain


Scan (TDS) and Real Time Scan (RTS) capabilities to the company’s 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.


TEST TIME REDUCTION According to Keysight, EMC testing requires detailed and exacting methodologies to ensure that all emissions are accurately measured. Long test times have a detrimental effect on 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. Keysight’s communications solutions group vice president and general manager of high frequency measurement R&D, Joe Rickert believes that the introduction of these new scan capabilities simplifies and exponentially reduces the time needed for test efforts in global EMC test laboratories. “With guaranteed compliance to the EMC standards, high 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 systems,” says Rickert.

❱ ❱ Signal analysis software forms one of the components for providing a comprehensive set of tools for generating signals, analysis, receiving and testing


NEW CAPABILITIES The N9048B PXE EMI receiver from Keysight is available with three frequency ranges up to 26.5 GHz providing extremely high sensitivity performance, which allows the detection of small signals close to the noise level, a phenomenon that is common in radiated emissions measurements The company has taken into account the global reach of certification requirements and the device has been made to be fully compliant with CISPR 16-1- 1:2015 and MIL-STD-461G (2015), ensuring that devices under test comply with worldwide as well as regional standards. The receiver has Time Domain Scanning (TDS) and accelerated TDS capabilities so that dwell measurement requirements can be met while reducing receiver scan and test times from several hours to just a matter of seconds, boosting the ability of test houses to meet increasingly stringent end user requirements for reduced test cycle times. For Real Time Scanning (RTS) the receiver gives full signal visibility, where the RTS provides gapless signal capture and analysis at up to 350 MHz bandwidth whilst simultaneously displaying the frequency domain, time domain and spectrogramme with three EMC detectors.


WIDE SCOPE IN TEST PROVISION USA based Keysight Technologies provides its EMC testing systems as part of its wider range of test and development products. With expertise in telecommunications, RFI and electronics testing, the company is able to provide technology for design simulation, prototype validation and manufacturing test as well as providing equipment for test houses. With more products requiring compliance testing and the constant push for reduction in development times, the development of improved EMC test and prototyping equipment is a perpetual challenge.
