The Radio Communication Tester R&S CMU 200 can be used to perform fast and accurate measurements of different mobile radio standards such as GSM, TDMA IS-136, CDMA IS-95A, CDMA2000, Bluetooth, WCDMA and AMPS. Even the basic functionality of the R&S CMU200, without any network dependent option, provides a couple of interesting possibilities for analyzing RF signals. Also in the so called RF function group the R&S 200 provides the same high accuracy as already known.
