5.13 Generating a Linear Slope Ramp Waveform
Generating a linear slope ramp waveform with the baseband generator is a function
that requires the additional option Baseband Power Sweep (R&S SMW-K542). The
main application field of these signals is amplifier tests, e.g. to determine the 1 dB
compression point of an amplifier.

5.14 Shifting and Boosting the Baseband Signal
The R&S SMW provides settings to frequency offset or power boost the baseband sig-
nals (internally generated and externally supplied) relative to the signals of the other
baseband sources.
5.14.1 About Baseband Offsets
The applied baseband frequency and phase offset and path gain affect the signal on
the output of the corresponding block, "Baseband" or "BB Input". The shifting of the
central frequency of the baseband signal is one of the tasks of the resampler.
