Single instrument measures wideband mmWave up to 110GHz

Believed to be the first single box multi-channel instrument for wideband mmWave measurements, the UXR series oscsilloscopes deliver fast, affordable, coherent analysis for wideband measurements up to 110GHz, says Keysight. The oscilloscopes accelerate the development of next generation mmWave communications, satellite communications and radar applications, adds the company.

mmWave and RF technologies have pushed frequencies above 100GHz; wide bandwidth needs reach 10s of GHz, explains Keysight. Technologies such as 802.11ay (WiGig), 802.11ad (gigabit wireless), satellite communications, radar and 5G, have frequencies that reach into the mmWave spectrum. The combination of wideband analyser and UXR scopes means measurements at these frequencies do not require the typical mix of instruments and down-converters, or the expense of purchasing a 1mm input oscilloscope with 80 to 110GHz of bandwidth.

The mmWave wideband analyser and UXR series oscilloscopes have a bandwidth pricing model that matches typical RF equipment; the price correlates with the analysis bandwidth needed. There is no need to purchase the full frequency range the oscilloscope hardware supports.

Deep captures exceed several seconds of time and accelerate processing up to 100x faster than non-decimated measurements while the availability of greater than 2.0GHz of digital down conversion (DDC) analysis bandwidth can be used in conjunction with available mmWave frequency extension options to extend DDC accelerated frequency ranges up to 110GHz.

The user can configure optional 5.0 or 10GHz analysis bandwidth windows within and above the UXR’s natively licensed bandwidth. This is limited only by the hardware’s maximum supported frequency range, says Keysight.

There is signal integrity with error vector magnitude (EVM) below 0.6 per cent for 5G new radio (NR) FR2 tests and one per cent for 802.11ay technologies, to reflect the true device under test (DUT) performance, without impairments caused by noise of the measurement system.

According to Brad Doerr, vice president and general manager of digital and photonics R&D for Keysight’s Communications Solutions Group: “Keysight’s UXR is the first oscilloscope on the market to address mmWave technologies and advanced applications such multiple input multiple output (MIMO) with up to four channels for the price of a 25GHz scope.”
