R&S CMX500 radio communication tester

The R&S CMX500 radio communication tester for 5G NR can be seamlessly integrated into an existing LTE test environment. It is also suitable for tests in 5G NR standalone (SA) mode.

The tester adds 5G NR signalling and RF testing to existing R&S CMW500 based LTE T&M solutions in labs. Users who already have a CMW500 or CMWflexx test system for LTE measurements can continue to use them and only need the tester as an extension box to perform tests on 5G NR signals. This set-up allows use cases to be tested in non-standalone (NSA) mode as specified in 5G NR option 3.

The tester measures the RF parameters of 5G NR transmissions and performs protocol tests. It has a modular design and a state-of-the-art, web-based user interface that makes it easy for users to configure the tester to meet their specific requirements.

Measurements in the FR2 range additionally require CMX HEAD30 multiband remote radio heads (RRH). The RRHs modulate the 5G NR IF output signal of the tester to produce RF signals in the millimetre wave range up to 43.5 GHz for 5G NR. The RRHs are connected directly to the tester and are easy to mount on the OTA test chamber.
