WORLD OF TEST
TEST INSTRUMENT FOR 5G VOICE SERVICES
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 ❱❱ The R&S CMX500 radio communication tester is ideal for testing voice services
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 8GHz and FR2 mmWave frequency range up to 50GHz 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 set-up 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.
UAV-MOUNTED MULTI-SENSOR DAYTIME IMAGING PAYLOAD
AeroVironment has introduced the Mantis i23 D, a multi-sensor daytime imaging payload compatible with the Raven B small unmanned aircraft systems (UAS). An enhanced daylight variant
of its predecessor, the Mantis i23, Mantis i23 D maintains its rugged design and uses the same modular interface to allow for quick and simple swapping between payloads with no software updates required to the avionics or ground control systems. At 380g, the ultralight
imaging system features dual 18 MP electro-optical sensors and 24X digital zoom, providing four times improved target detection over the current Mantis i23 payload during daytime missions.
Through its advanced suite of
sensors, extended zoom capability, onboard processing and digital imaging stabilisation, the Mantis i23 D
payload allows operators to increase aircraft imaging range without compromising image quality.
With its primary field of

application in the defence and security industry, there are clear spin-off benefits for industrial and environmental monitoring applications.
