It is also possible to create and output a blank segment, i.e. segments containing a
zero signal.
Typical applications for the multi-segment mode are described in section Chap-
ter 4.8.4, "How to Create and Work with the Multi-Segment Waveform Files",
on page 345.
4.8.2.1 Multi-Segment Waveforms Processing
Processing of the waveform is triggered by the "Create" or "Create and Load" function.
To process the waveform, the instrument loads the entire multi-segment waveform into
the memory. It is therefore possible to alternate between the individual waveforms
without delay due to loading. You can define the output order of the segments, as well
as the segment intended to be output at any given moment.
When the created waveform is loaded, the graphical interface displays information on
clock rate, number of samples and creation day. You can also acquire information
about the waveform in the dedicated "Waveform Info" dialog.
4.8.2.2 The ARB Sequencer Mode
If high switch over speeds is required, the test signals can be continuously scrolled
through with the aid of an external trigger or by applying a predefined “Play List”. The
R&S SMW provides the possibility not only to define a sequence of different segment
but also to determine whether a segment is played once or repeated several times and
to adjust the transition between the segments.
For the correct and fast processing and for seamless transition between the multiple
waveforms, segments with a common sample rate are required. If the combined wave-
forms features different sample rates, they have to be adapted to a common sample
