T&M specialists Rohde & Schwarz and VIAVI Solutions announced verification of their respective test equipment on correct implementation for 5G NR and LTE. The verification is based on the R&S CMX500 5G NR wideband radio communication tester by Rohde & Schwarz and the TM500 network tester for user equipment (UE) emulation by VIAVI.
5G NR uses a combination of various features, functions and complex algorithms, making it vital for UE manufacturers to perform extensive testing of 5G mobile devices before bringing them to the market. The cooperation ranges from RF performance testing, to protocol stack verification and to maximum IP data throughput tests to support Rohde & Schwarz and VIAVI customers such as chipset and device manufacturers, operators and test houses as well as network infrastructure clients.
Using the R&S CMX500 from Rohde & Schwarz as network infrastructure emulator alongside the VIAVI TM500 UE emulator is a versatile alternative to a real device. This enables both companies to achieve their goals in providing customers with stable, mature and wider 5G 3GPP feature coverage at an accelerated rate. The test instruments enable the testing of complex 5G signaling features for NSA mode or SA mode in FR1. This includes features like DSS (dynamic spectrum sharing), LTE advanced and 5G NR carrier aggregation combinations, over-the-air (OTA) testing, but also feature verification of high-bandwidth tests in FR2 spectrum.
