The combination of R&S® CMU200 and R&S® UPV is in use for various tests of mobile phone speech functionality, such as acoustic tests according to 3GPP 26.132 or speech quality tests according to ITU-T P.862 (PESQ®) or ITU-T P.863 (POLQA®). This application note explains how to replace the R&S® CMU200 in these tasks with R&S® CMW500.

Recent mobile test methods could not evaluate the quality of data reduced speech signals with different coded and decoded signals. The Perceptual Evaluation of Speech Quality (PESQ) provides the solution for this measuring problem. CDMA2000 PESQ is an add-on tool for CMUgo for automatic measurement of the PESQ for CDMA2000 mobile phones according to recommendation ITU-T P.862.1 featuring selectable fading profiles and variable Additional White Gaussian Noise (AWGN).

The Universal Radio Communication Tester R&S®CMU200 can perform most of the CDMA2000 1xEV-DO access terminal (AT) tests specified in the standard IS-866-A on its own. Some tests require additional instruments. This application note shows how to perform these tests easily with the remote-control software CMUgo, using the R&S®CMU200 in combination with R&S®SMU, R&S®AMU, R&S®SMJ or R&S®SML signal generators, and R&S®FSQ, R&S®FSU, R&S®FSP, R&S®FSL or R&S®FSMR spectrum analyzers.

Most of the tests specified in the standard TIA-98 that a CDMA2000 mobile station has to fulfill can be performed by the Universal Radio Communication Tester R&S®CMU200 without further assistance. Other tests, however, require additional instruments, for instance for generating interfering signals. Some tests of the standard TIA-98 need features that a tester optimized for production cannot offer, for example high dynamic spectrum analysis up to 12.75 GHz. This Application Note shows how to perform these tests easily with the remote-control software CMUgo, using the R&S®CMU200 in combination with R&S®SMU, R&S®SMJ, R&S®SMIQ, or R&S®SML signal generators, and R&S®FSQ, R&S®FSU, R&S®FSP, or R&S®FSL spectrum analyzers. New test items and sequences will therefore be included in the CMUgo software v1.9.8 to remote-control the R&S®CMU200, as well as the signal generators and spectrum analyzers. They are presented in this Application Note.
