5.8.4.2 Multi Segment Waveforms
To fulfill the requirements of some test systems and to enable rapid alternation between
different waveforms with differing test signals, the R&S Signal Generator provides the
functionality to generate multi segment waveform files. A multi segment waveform is a
combination of multiple waveforms called segments. Each segment represents a com-
pletely independent waveform that can be output with its own marker and clock settings.
The entire multi segment waveform is loaded into memory. The segment intended to be
output at any given moment can be selected by the user. It is therefore possible to alter-
nate between the individual waveform segments without experiencing any delay due to
the loading operation.
If very high switchover speeds are required, the test signals can be continuously scrolled
through with the aid of an external trigger or by applying a predefined “play list”. For this
purpose the segments must have a common sample rate. If the combined waveforms
have different sample rates, they can be adapted to a common sample rate by resam-
pling. By the same procedure the instantaneous amplitude of the various waveforms can
be scaled to a common RMS level.
