Electronics Engineering Software Test & Measurement software testANRITSU SmartStudio NR (SSNR) MX800070A control software has been enhanced to support 5G-device Evolved Packet System (EPS) Fallback tests using the Radio Communication Test Station MT8000A. With the new functionality, the MT8000A/SSNR environment simplifies evaluation and reduces cost-of-test when verifying 5G New Radio (NR) UE being developed for emerging applications. With a built-in IMS server function, engineers can test the IMS functions of their 5G device designs using SSNR without configuring a complex test environment. SSNR serves as control software for the MT8000A. It emulates 5G NR Standalone (SA) network conditions and communication between a 5G network and mobile terminal operating in VoLTE in EPS Fallback mode to drop out of the 5G SA connection to LTE for an incoming VoLTE voice call.
