"Same Segment"
The processing of the multi-segment waveform file is similar to the
processing of a non-multi segment waveform, i.e. there is no switch-
ing to consecutive segment upon the receiving of a trigger event.
To trigger switching between the segments, change the segment
index in the "Segment" field.
"Next Segment"
The current segment ceases to be output when a trigger event for a
new segment occurs, and the new segment starts to be output after a
system-imposed signal gap.
"Next Segment Seamless"
The new segment is not output until the whole of the current segment
has been output (wrap around), i.e. the signal transition is seamless.
"Sequencer"
The waveform files are processed according to the order and repeti-
tion cycles defined in the special sequencing list file (*.wvs)
assigned to the multi-segment waveform file.
This “play list” is defined in the Multi-Segment Waveform Sequencing
dialog.
Remote command:
[:SOURce<hw>]:BB:ARBitrary:TRIGger:SMODe on page 939
Next Segment Source
Determines whether the next segment is switched upon receiving of an external trigger
signal or upon executing of software next segment trigger (see Figure 4-20).
This parameter is disabled, if a sequencing play list is enabled.
"Internal"
Switch over to any segment is triggered manually with the "Execute
Next Segment" function.
"Global Next Segment 1/2"
(requires option R&S SMW-B10)
The trigger event for switching to the next segment is input as config-
ured on one of the USER connectors (see Chapter 11.2, "Configuring
the Local and Global Connectors", on page 661).
Remote command:
[:SOURce<hw>]:BB:ARBitrary:WSEGment:NEXT:SOURce on page 937
Level Mode
Sets how the instrument levels the individual segments in a multi-segment signal. The
parameter is important, if waveforms with different crest factors are used.
"Highest"
All segments are output at the highest available crest factor.
"Unchanged"
Each segment is output with the crest factor defined in its waveform
file.
Remote command:
[:SOURce<hw>]:BB:ARBitrary:WSEGment:LMODe on page 937
