The following events cause a switch over:
●
An external next segment trigger event
●
An internal segment trigger, that is a change in the segment index in the "Segment"
field
Use the parameter Next Segment Mode to define whether the new segment is gener-
ated immediately or only after the previous segment has been fully generated (wrap
around). The subsequent trigger event after the last segment causes the first segment
to be output again.
For more information, see Chapter 5.10.2.5, "Impact of the Trigger Settings and Next
Segment Settings", on page 355.

Next Segment Mode
Defines the way the switch over between the segments in a multi-segment wave-
form is executed.
The regular trigger mode for starting the waveform generation and triggering the
whole multi-segment sequence is set with the parameters in the "ARB > Trigger" tab.
The segment currently being output is displayed at "Current Segment". The "Trigger
Example" graph displays schematically the waveform output, depending on the activa-
ted trigger and the next segment settings.
For background information, refer to Chapter 5.10.2.5, "Impact of the Trigger Settings
and Next Segment Settings", on page 355.
For detailed information on how the regular trigger signal affects the multi-segment
waveform processing in combination with the different values for "Next Segment
Mode", refer to Chapter 5.10.5, "Reference to Triggering of Multi-Segment Wave-
forms", on page 378.
Note: The seamless switch over and the sequencer mode require segments with equal
sample rate.
"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"
If all segments have the same sample rate, 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.
