Rohde & Schwarz has developed the R&S®CMsquares software, a one-platform solution for all 5G NR test equipment that enables a unified test environment for signalling and non-signalling testing through all stages of 5G device production. It is controlled via a web GUI and can carry out test configuration, parameterization, measurements as well as test execution in a single environment.
R&S®CMsquares has an intuitive and flexible web-based user interface which combines everything that is required for 5G NR testing. It has a dashboard where all types of applications can be accessed. The standardized GUI provides a unified user experience for all Rohde & Schwarz 5G radio communication testers. It can be used for all facets of device testing and can also control all-new 5G radio communication testers.
With R&S®CMsquares, users can access measurement tasks in separate measurement squares. The DUT is always in focus with R&S®CMsquares and with this DUT-centric approach, it is very easy to keep an overview of even complex test scenarios, test environments and measurement tasks. The interface includes as many squares as needed: for measurements, graphical outputs and statistical views, network layout and configuration, RF connection, message analyzer, test sequencer, scripting and more. The layout can be configured for your personal preferences at any time.
Through the software, users can access pre-installed test scenarios and customize the software according to their requirements. The software can be used for all 5G requirements like RF measurements, protocol verification, and end-to-end data testing. The interactive callbox mode helps rapidly connect to a device under test, alter network parameters on the fly, analyze real-time RF TX/RX measurements and trace protocol stack messages on all protocol layers or generate statistics for data throughput testing with a variety of chart diagrams.
All measurements can be operated manually in the workspace or built as test sequences in the integrated R&S® CMsequencer graphical scripting interface. Test routines can be remotely controlled via XLAPI and SCPI interfaces. This makes the R&S CMsquares an advantageous software solution, with unique modules for all signalling use cases ranging from R&D design stages up to end-to-end application testing, production and conformance tests.
The R&S®CMsquares test software provides all necessary technologies to enable VoLTE and VoNR audio measurements in 5G SA and NSA modes, as well as ViLTE and ViNR video measurements. It has an integrated IMS server (IP multimedia system) allowing it to perform internal loopback along with audio quality testing with an external audio analyzer in IP forward mode.
