7. Select "ARB > Trigger (MSW) > Trigger Source = Internal"
The segments are played back (output) as defined in the sequencing list, i.e. the
switch over to the next segment is performed automatically according to the rules
and segment order defined in the "Sequencing Play List".
To add marker signals
We assume, that a multi-segment sequence composed of the segments Seg#0 [1],
Seg#3 [2], Seg#2 [1] is created and loaded in the ARB (see "To configure a multi-seg-
ment sequence using the play list function" on page 377). The multi-segment sequence
starts with Seg#0 and this segment is output once. The instrument is operated man-
ually, the ARB generator is in active state, and the instrument output is switched on.
To add marker signals at the beginning of each segment and at the beginning of the
sequence (see Figure 5-32), two additional marker signals, "Marker 2" and "Marker 1",
are enabled and inserted into the multi-segment waveform.
1. Select "ARB > Marker > Marker Mode > Marker 1/Marker2 = Unchanged" to enable
taking over of the marker signals defined inside the multi-segment sequence.
If necessary, adjust the marker delay settings.
2. Select the "Block Diagram > Trigger/Marker/Clock" and map the "Logical Signals >
Marker 1/Marker 2" to the desired connectors ("Global Connectors > User x >
Direction = Output" and "Signal = Baseband Marker 1/Baseband Marker 2")
3. In the "ARB > Multi Segment > Level/Clock/Marker" dialog, select "Segment
Marker = Ignore"
4. Enable "Level/Clock/Marker > Sequence Restart = Marker 1"
5. Enable "Level/Clock/Marker > Segment Restart = Marker 2"
An extra restart marker signal is generated at the beginning of each segment and
the beginning of the waveform. These restart markers overwrite the existing Marker
1 and Marker 2 trace signals defined in the waveforms of the individual segments.
5.10.5 Reference to Triggering of Multi-Segment Waveforms
Signal generation of multi-segment waveforms takes place differently according to the
trigger selected in the "ARB > Trigger In" section. The sections provide a detailed
explanation of the effect of a trigger event on the multi-segment waveform processing,
depending on the enabled "Next Trigger Mode". Refer to Chapter 5.10.2.5, "Impact of
the Trigger Settings and Next Segment Settings", on page 355 for background informa-
tion.
5.10.5.1 Triggering in "Next Trigger Mode = Same Segment"
Depending on the trigger setting, the currently selected segment is continuously output
either immediately or after a trigger event.
