New test system for radio resource management - 3G/UMTS manufacturers, operators and service providers able to carry out all important RRM tests

The new R&S CRTU-RRM system comprising various test and measurement instruments makes it possible for the first time to perform all RRM test cases in TTCN (tree and tabulator combined notation) source code without any problems.

TTCN implementation both ensures maximum control of the functionality and unambiguously determines the signalling behaviour of the test equipment. 3G/UMTS manufacturers, operators and service providers are thus able to carry out all important RRM tests on 3G/UMTS user equipment in absolute compliance with the specification.

The R&S CRTU-RRM system in its base configuration comprises the Protocol Testers R&S CRTU-W and R&S CRTU-G for simulating the WCDMA and GSM cells, as well as a baseband fading simulator and a spectrum analyzer ensuring extremely high level accuracy. By combining two R&S CRTU-W, as many as six WCDMA cells can simultaneously be simulated in line with the test specification. The system is controlled by means of a graphical user interface. A project explorer configures the individual tests and groups them in special test sessions. Equipment control and test sequence, including all associated parameters, are of course handled automatically.
