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.

In addition to frequency, power and long-term stability, short-term stability or its equivalent, phase noise, is an important characteristic of signal sources. For example, the phase noise of conversion oscillators of receivers obtained in the presence of a strong signal determines adjacent-channel sensitivity. In the case of transmitters, the phase noise of the oscillator together with the modulator characteristics is responsible for the power generated in adjacent channels. The phase noise of oscillators or synthesizers and the relevant measurements therefore play an important role in radio transmission systems.

Measuring the spurious emissions of transmitters used in GSM, DCS 1800 and PCS 1900 networks requires highly complex test setups since con-ventional spectrum analyzers do not have the necessary dynamic range. To obtain this range, notch filters are used to suppress the useful sig-nal. The spectrum analyzers of the FSE family make it possible for the first time to verify com-pliance with stipulated limit values for spurious emissions within the transmission band and out-side the reception band without the use of notch filters. The measurement problem and its solution by means of FSE are described in the following by way of the example of a GSM base station.

Power amplifiers in digital TDMA mobile phones are fed with current only during the active slot to save power. Using conventional measuring equipment, the noise figure, an important parameter in power amplifiers, can only be determined with the amplifier in continuous operation. However, continuous operation can lead to amplifier overload and produce distorted results. Now there is a convenient way of determining the noise figure of amplifiers with pulsed power supply: using a Spectrum Analyzer (FSP or FSE or FSIQ or ESI), Noise Measurement Software FS-K3 and a function or pulse generator.
