Rohde & Schwarz CMX500 5G radio communication tester

Users of Bluetest reverberation test systems (RTS) can now use the Rohde and Schwarz CMX500 5G NR radio communication tester for 5G FR1 MIMO over-the-air (OTA) measurements.

With the CMX500 integrated in the Bluetest Flow control software, users can measure throughput as well as receiver sensitivity and output power on multicarrier devices with up to 4x4 MIMO. The reverberation chambers from Bluetest in combination with the CMX500 now enable developers and manufacturers of 5G components and devices to perform MIMO stress testing under realistic conditions with high data rates.

Bluetest, based in Gothenburg, Sweden, specialises in reverberation chambers such as the RTS65 for efficient OTA performance evaluation of the device under test (DUT). Unlike anechoic test chambers, reverberation chambers reflect an RF signal inside the chamber to the greatest possible extent to create a Rayleigh faded multipath RF environment similar to real-world indoor and city conditions. The set-up is run by the Bluetest Flow software, an integrated test environment for complex wireless solutions. It features characteristics such as an integrated result database, comprehensive customisation options and a full-fledged scientific computing environment. It supports legacy systems as well as the latest wireless standards such as 5G NR.

It emulates the network in the test set-up, allowing both non-standalone and standalone testing in FR1 and FR2. The modular design adds 5G capabilities to LTE-based legacy solutions such as the CMW500 wideband radio communication tester or the CMWflexx platform.
