High-frequency EMI receiver


eysight Technologies has extended the frequency range of the company’s N9048B PXE Electromagnetic Interference (EMI) Receiver from 26.5GHz

to 44GHz enabling customers to meet current and emerging compliance testing requirements according to various standards bodies, including MIL-STD-461G and FCC Part 15. Both of these are

American standards, one being the military standard and the other relating to the Federal Communications Commission. Both standards are widely adopted both inside and outside military applications and not confined to the USA. Comparable UK and European Union standards as well as the International Electrotechnical Commission’s CISPR (International Special Committee on Radio Interference) technical standards such as CISPR 16 are catered for in the increased frequency range offered by the new Keysight equipment.

AUTOMOTIVE AND 5G APPLICATIONS The cellular (5G) and automotive industries need to make use of higher frequencies to deliver new applications requiring increased spectrum resources to carry large amounts of data at faster speeds. The automotive industry is placing

greater demand on EMC testing capabilities as the RF environment of vehicles becomes more crowded and complex. The effective functioning of advanced safety features in vehicles as well as autonomous control require high speed, low latency communications and 5G is

New EMC instrument for test houses provides greater emitted frequency

measurement capability

performing the higher frequency tests that they need. “Offering such high levels of

performance in combination with EMC focused application software, Keysight’s 44GHz PXE enables certification labs to confidently handle any new product that requires compliance testing and adherence to the CISPR 16-1- 1:2019 and MIL-STD-461G (2015) standards,” he says. Keysight’s PXE is a standards-compliant EMI receiver and diagnostic signal analyser that provides the accuracy, repeatability and reliability needed to test with confidence. Now supporting a frequency range of between 2Hz and 44GHz, Keysight’s PXE EMI Receiver delivers:

❱❱ The N9048B PXE electromagnetic interference (EMI) receiver from Keysight

Technologies offers increased frequency range measurement to meet industry demand

widely seen as the pivotal technological element that will enable the full development of the connected autonomous vehicles (CAVs) of the future. 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). According to Joe Rickert, vice-president

and general manager of high-frequency measurement R&D for Keysight’s communications systems group, the PXE receiver provides users in these demanding industries with the capability of

n 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; n Full compliance with CISPR 16-1-1:2019 and MIL-STD-461G (2015), ensuring devices comply with new worldwide and regional standards; n 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. n Full signal visibility, where the real time scan (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 enabling customers to better understand their signals.
