Set up as GNSS simulator, R&S CMW500 wideband radio communication tester and R&S SMBV100A vector signal generator allow manufacturers of automatic in-vehicle systems to perform pre-conformance tests on ERA GLONASS modules in lab. R&S CMW-KA095 software simulates PSAP and controls R&S CMW500 emulating wireless communications network. With test solution, users can verify whether IVS modem can successfully initiate emergency call, transmit correct MSD, and establish voice connection with PSAP.
