HEAD acoustics is using the R&S CMX500 to accelerate testing of 5G NR voice service (VoNR)
The voice and audio analysis expert HEAD acoustics has chosen the 5G test system from Rohde & Schwarz for verification of voice and audio services of 5G mobile devices. The R&S CMX500 5G one-box signalling tester features a significantly reduced footprint and easier handling combined with debugging and analysis capabilities, which support the end users’ testing of voice services.
The CMX500 offers a comprehensive tool set for audio testing. When combined with the labCORE hardware platform from HEAD acoustics and their ACQUA measurement and analysis software, the full setup allows audio acoustics testing of voice services in both 5G (VoNR) and 4G (VoLTE) networks. This enables manufacturers of 5G capable devices to test the voice quality of their devices at an early stage before market introduction.
Rohde & Schwarz has addressed the needs of audio test labs with its product that allows 5G NR devices to be tested in both standalone (SA) and non-standalone (NSA) TDD and FDD mode. The R&S CMX500 supports 5G FR1 frequency range up to 8 GHz and FR2 mmWave frequency range up to 50 GHz in one instrument and provides the required features and codecs for VoLTE and VoNR calls. With new features such as the Connection Selection, configuration and adaptation of the device under test (DUT) to the test setup becomes easier than ever, thanks to very easy handling and visualisation of the DUT antenna connection with the RF connectors of the R&S CMX500.
The HEAD acoustics labCORE system is connected via Ethernet using the integrated IP forward mode of the internal R&S CMX500 IMS server, specifically developed in a joint cooperation for this case. This allows users to forward the voice data of a call established to the labCORE system for detailed voice quality analysis. However, an analogue connection with the labCore system is also supported in case the labCore system is not equipped with the IP interface.
