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.

Verification of baseband data is an important step in the early development phase of LTE/LTE-A-ready products. Comparison values for baseband data (test vectors) from other sources can be very useful in order to verify the correct implementation of the standard. Option K81 for the R&S®SMx200A vector signal generator offers sample data for LTE at the bit level. The reference data enables users to test their own implementation of the specification. The LTE bit stream verification program shown here uses data generated by this option and offers a (bitwise) comparison with bit streams generated for an LTE downlink signal. Therefore it demonstrates, how easy the option R&S SMx-K81 can be integrated into the simulation and design process during the development of LTE/LTE-A handsets or base stations.
