R&S Focuses on 5G/6G Component Test at IMS2022

June 18, 2022
Rohde & Schwarz will showcase new EVM optimization techniques for 5G FR2, 6G D-Band component test, the latest OTA test chamber, and many additional new products.

This article is part of our IMS2022 coverage.

In Booth 7056 at IMS2022, Rohde & Schwarz will demonstrate a broad range of new test solutions that cover the mmWave frequency range and meet the latest industry demands imposed by higher frequencies, wider bandwidths, and more complex modulation schemes. Demos will include new approaches to optimizing EVM performance, 6G D-band system and component characterization, and the latest CATR-based OTA test solution.

One don’t-miss demo is the company’s latest solution for optimizing error vector magnitude (EVM) capabilities, based on the R&S SMW200A vector signal generator (VSG), which now covers up to 67 GHz, and the R&S FSW signal and spectrum analyzer. Accurately measuring EVM has become a key specification for both the device under test (DUT) and the test instrumentation, as it encapsulates many critical test parameters. A new front end for Rohde’s FSW brings extremely high EVM measurement accuracy for wideband modulated signals in the mmWave range. This makes the solution well suited for testing any high-end communication component or systems, including 5G NR FR2 or IEEE 802.11ay/ad chipsets, amplifiers, user equipment, and base stations.

The R&S FSW is complemented by the R&S SMW200A vector signal generator. When it comes to creating complex digitally modulated signals, 44 GHz has been the limit for high-accuracy standalone vector signal generators. Higher frequencies have only been possible with additional external equipment and limitations in accuracy. Now, the R&S SMW200A from Rohde & Schwarz dramatically raises the limits for generating wide bandwidth signals of high quality with two new options for maximum frequencies. The 100-kHz-to-56-GHz option covers all currently used 5G frequencies, plus earth-to-satellite applications. The 100-kHz-to-67-GHz option also supports planned higher frequency 5G bands, the 60-GHz WiGig band, and inter-satellite links.

Another demo will show an R&S ZNA vector network analyzer (VNA) used for 6G D-band system and component characterization. Key industry players have identified the D-band, ranging from 110 GHz to 170 GHz, as a candidate frequency band for 6G mobile communications, as well as for future automotive radar applications.

Additionally, show attendees will get a close look at the R&S ATS1800C CATR-based 5G NR mmWave over-the-air (OTA) test chamber, which provides the ideal environment for testing 5G FR2 antennas, modules, and devices from R&D to conformance. Equipping the unit with two side-chamber extensions forms a unique 3D quiet zone, with which the test solution even supports on a very small footprint RRM measurements including multiple angles of arrival (AoA).
