The R&S CMX500 integrated in the Bluetest Flow control software provides a stable and reliable measurement throughput

The reverberation chambers from Bluetest in combination with the R&S CMX500 now enable developers and manufacturers of 5G components and devices to perform MIMO stress testing under realistic conditions with high data rates.

Bluetest is a Sweden-based company that 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 setup 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, and supports legacy as well as the latest wireless standards such as 5G NR.

The R&S CMX500 emulates the network in the test setup. It is a future-proof solution for 5G NR testing, allowing both non-standalone and standalone testing in FR1 and FR2. Featuring a modular design, the R&S CMX500 adds 5G capabilities to LTE based legacy solutions such as the well-established R&S CMW500 wideband radio communication tester or the R&S CMWflexx platform.

Rohde & Schwarz and Bluetest have been cooperating for many years. The two companies worked earlier on integrating the R&S CMW500 tester into the Bluetest Flow software to support LTE, LTE-A and many other cellular and non-cellular wireless standards. This successful cooperation led to the next logical step – the integration of the R&S CMX500 for 5G NR FR1 measurements.

“We are happy to continue our cooperation with industry-leading partner Bluetest and to provide our valued clients with top-class 5G test solutions. For Rohde & Schwarz, this integration is a welcome addition that enhances our already comprehensive 5G test and measurement portfolio,” said Christoph Pointner, Senior Vice President Mobile Radio Testers at Rohde & Schwarz.

“The R&S CMX500 and the popular RTS65, or the larger RTS85/RTS95 walk-in chambers, together create a user-friendly, yet powerful, test setup for RF R&D of 5G devices of various sizes including larger IoT equipment,” said Klas Arvidsson, Bluetest Product Manager.
