Keysight’s UXR box analyzes mmWave 1x1, 2x2 MIMO 5G NR links

Keysight's UXR-Series oscilloscopes, with optional mmWave Wideband Analysis functionality, "bring signal, spectrum, and digital capabilities together," asserts the company.

Keysight Technologies, Inc. (NYSE: KEYS), a technology company serving enterprises, service providers and governments, has introduced a flexible single channel instrument specifically designed to accelerate development of 5G mmWave communications, satellite communications, and radar applications.

“Keysight’s UXR...can easily and accurately analyze millimeter-wave 1x1 and 2x2 MIMO 5G NR communication links. It has a very low error vector magnitude (0.2-0.9%) for 200 MHz-5 GHz bandwidth signals, even at -40 dBm input power and at 67 GHz,” asserts Dr. Gabriel M. Rebeiz, Distinguished Professor and Member of the National Academy at the University of California, San Diego.

Dr. Rebeiz adds, “We connect our 5G phased-arrays to the UXR without any external amplifiers or filters, run the 89600 VSA software and start measuring. It has cut our measurement time from hours to just minutes. I cannot imagine how a state-of-the-art 5G lab can operate today without Keysight’s UXR.”

Keysight’s latest addition to the company’s UXR-Series of oscilloscopes, the UXR0051AP Infiniium UXR-Series Oscilloscope, offers a frequency range of 110 GHz and 5 GHz of standard analysis bandwidth, and provides fast, flexible analysis of wideband measurements.

Keysight says its UXR-Series oscilloscopes, with optional mmWave Wideband Analysis functionality, "deliver the signal integrity, versatility, affordability, and performance needed to bring signal, spectrum, and digital capabilities together, within a single instrument."

Keysight says its UXR0051AP Infiniium UXR-Series Oscilloscope offers a superior -158 dBm/Hz displayed average noise level (DANL) from 28 GHz to 85 GHz which enables golden receiver quality error vector magnitude (EVM) measurements on low power wideband signals. The UXR0051AP directly measures wideband signals with up to 10 GHz bandwidth and fundamental frequencies as high as 110 GHz, without the need for external downconverters, for high quality wideband analysis. 

The new unit supports instant upgradability to two independently configurable phase coherent channels for easy multiple input multiple output (MIMO) measurement support. The instrument features a high-definition, 10-bit analog-to-digital converter (ADC) with 16-bit Digital Down Conversion (DDC) I/Q data output to ensure high mmWave measurement accuracy.  

256 GSa/s real-time or 3,200 MSa/s complex sample rates deliver a very wide 110 GHz frequency range and 2.16 GHz DDC analysis bandwidth. Flexible mmWave extension and DDC bandwidth license options enable performance and affordability for oscilloscope based mmWave wideband analysis. 

“To satisfy the demand for faster speeds and increased bandwidth, mmWave technologies are evolving with techniques such as MIMO and phased array antennas,” concludes Brad Doerr, vice president and general manager of digital and photonics R&D for Keysight's Communications Solutions Group. “Keysight recognized the need for a cost-effective one channel oscilloscope with dynamically configurable bandwidth to support today’s single-channel mmWave wideband measurement requirements. The new oscilloscope can instantly expand to two phase coherent channels, enabling customers to easily support this emerging multi-channel evolution."
