Analyzing 5G New Radio Uplink Signals

RS FSW UA30 August 2018 - Rohde & Schwarz introduced a new solution for analyzing 5G NR uplink signals in line with the latest 3GPP specifications. The R&S FSW-K145 5G-NR UL measurement application for the R&S FSW signal and spectrum analyzer is used to develop 5G user equipment and components such as power amplifiers. It complements the existing R&S FSW-K144 5G NR downlink measurement application, which is used to test 5G base stations.

The R&S SMW-K144 5G NR option for the R&S SMW200A vector signal generator can generate the required signals for uplink and downlink receiver tests. All three 5G NR signal generation and analysis options now support 15.2.0, the most recent version of the 3GPP standard.

With the new R&S FSW-K145 5G-NR UL measurement application, the R&S FSW signal and spectrum analyzer captures and analyzes 5G NR uplink signals from user devices. The application supports multiple component carriers and multiframe signals. When used together with the existing 5G NR signal generation and analysis options, it lets developers test compliance with the latest 3GPP standards, enabling them to validate user devices including 5G modems, mobile phones, IoT devices and base stations in ways that cannot be achieved with general-purpose solutions on the market. With these options for signal generation and analysis, testing to 3GPP 5G NR specifications TS 38.211/ TS 38.212/ TS 38.213/ TS 38.214 is now supported for the latest versions of these standards, including version 15.2.0 from June 2018.

Uplink characterization benefits from the outstanding test and measurement capabilities of the R&S SMW200A vector signal generator and the R&S FSW signal and spectrum analyzer. The R&S SMW200A is the first of its kind to offer 2 GHz fully calibrated wideband signals up to 40 GHz in a single box. Its intuitive operating concept and smart help functions facilitate the configuration of complex signal scenarios such as 5G NR, directly from the instrument.

Equipped with the new R&S FSW-K145 5G NR UL signal analysis option (and/or the R&S FSW-K144 5G NR DL signal analysis option), the R&S FSW supports sub-6 GHz and mmWave signals with different subcarrier spacing and carrier bandwidths. Extending its internal analysis bandwidth up to 2 GHz, the R&S FSW-B2001 allows R&D users to investigate wideband signals in detail without the need for an external digitizer.

The R&S SMW-K144 5G NR signal generation option (covering downlink and uplink signals), the R&S FSW-K144 5G NR downlink and the new R&S FSW-K145 5G NR uplink signal analysis option are now available from Rohde & Schwarz.
