This user manual contains a description of the functionality that the application provides, including remote control operation.
Welcome to the R&S SMCVB-K548 option
Accessing the required settings
Reduces the crest factor of a baseband signal through clipping the high signal
peaks and filtering the waveform afterwards.
Can be applied to any waveform file loaded in the arbitrary waveform generator.
It uses an iterative process to reach the desired crest factor delta.
It is possible to adjust the filter characteristics. In simple mode, you can specify the
channel spacing and signal bandwidth. Alternatively in the advanced filter mode
you can specify the lowpass filter through passband and stopband frequencies.
All functions not discussed in this manual are the same as in the base unit and are
described in the R&S SMCV100B user manual. The latest version is available at:
