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.

The fact that cable TV networks are generally located in densely populated areas or extend over large geographical regions makes the presence of line extenders at regular intervals a necessity. Cascading large numbers of amplifiers however calls for excellent noise, SWR and intermodulation distortion specifications for the integrated amplifiers in order to avoid quality of service dropping below minimum acceptable levels. Composite second order, composite triple beat & cross modulation are commonly used figures to specify the performance of CATV equipment. In this application note we describe how to determine these figures with the aid of R&S SMU200A or AFQ100A and SMV vector signal generators.
