Power amplifiers for WCDMA/3GPP base stations should have the best possible spectral purity and smallest intermodulation distortion, in order to prevent disturbance of the neighbouring channels. To test such amplifiers, signal generators are required that can generate WCDMA signals with low noise and intermodulation over a very wide dynamic range. The R&S SMIQ03HD signal generator with its outstanding Adjacent Channel Leakage Ratio (ACLR) performance is especially designed for these applications. This application note describes how to use SMIQ03HD to get the best performance with 3GPP single and multi carrier signals.

Testing multi carrier power amplifiers of the 3rd Generation requires test signals with a high dynamic range. This application note describes how a 4 carrier 3G WCDMA signal can be generated and measured with the application software SET_MC4. The software sets up to 4 SMIQ03HDs to generate the signal, and an FSU or FSQ to immediately evaluate and analyze the Adjacent Channel Leakage Ratio (ACLR) of the power amplifier. The setups are controlled remotely.The SET_MC4 source code is also included. Modify the code to meet your individual requirements or adopt the IEEE-commands into your own setup script.

This application note describes how to use the Rohde & Schwarz software tool ‘RsBatchConvert.exe’ for the conversion of binary data or WinIQSIM generated AMIQ waveforms into the new waveform format. The tool not only rescales I/Q data contained in the file but also changes the K-option requirement from WinIQSIM Kxx to the new WinIQSIM2 K2xx options. Thus, new instruments with installed K2xx options may be used to continue using existing waveform files.

This Application Note describes measurements compliant with the cdma2000® base station standard described in 3GPP2 C.S0010 / TIA/EIA-97 / ARIB STD-T64-C.S0010.The primary focus is on solutions for generating and analyzing cdma2000® signals. The special characteristics that make the selected signal generators and signal analyzers eminently suitable for this purpose are detailed, and remote control programming is demonstrated by a free of charge program.
