The R&S CMU300 combines high-precision Node B parameter tests with layer 1 signalling processes for the first time. Thus, you can now test Node Bs under more realistic conditions as it was possible with existing concepts. This document describes the new measurement functions and provides an overview of their applications.

GSM Adaptive Multi-Rate (AMR) tests can be performed by using the R&S CMU300 as of software version V3.65. This document describes the scope of functions of the AMR Testing R&S CMU-K37 software expansion option.

This Application Note provides an overview of the Bit Error Rate (BER) test capabilities of the Universal Radiocommunication Tester CMU300 on GSM / EDGE Base Stations. It includes information about measurement principles, the supported test environment and channels, CMU settings, operation, and ordering information.

The Radio Communication Tester R&S CMU300 and Coverage Measurement System R&S ROMES provide a wide range of possibilities to check the HSDPA air interface and network quality. The measurement results that can be obtained with the aforementioned solutions ensure flawless operation of HSDPA services from the start and longstanding customer acceptance of the new technology.

Testing the RF parameters of a WCDMA base station during the network rollout phase ensures subsequent trouble-free operation of networks as a basic prerequisite for general UMTS customer acceptance. This document describes a complete solution for testing the main transmission and reception parameters according to Specification 3GPP TS 25.141 FDD R99 on the basis of the R&S CMU300 Radio Communication Tester (RF measurements) and the NetHawk RNC/Iub Simulator (base station controller). The solution presented here is particularly recommended for installation measurements and regression tests on new UMTS system components.

The use of Rohde & Schwarz device drivers under VEE software is not complicated. However, a number of factors are involved, the errors that occur are often difficult to diagnose. This application provides easy and detailed support for installation and troubleshooting using National Instruments or Agilent GPIB boards.

This application note has been replaced by application note 1MA074 RSCommander.
