Next Segment
Selects the waveform segment to be output next. It determines the start segment when
switching on the ARB and enables switchover to any other segment.
The switchover is performed either after receiving an external next segment trigger
event or, for the internal trigger case, by changing the segment index in the "Next Seg-
ment" field. The definition whether the new segment is generated immediately or only
after the previous segment has been fully generated (wrap around) is determined by
the parameter
The segment currently being output (segment index and filename) is displayed at "Cur-
rent Segment". The subsequent trigger event after the last segment causes the first
segment to be output again.

Next Segment Mode
Sets the segmented trigger mode of a multi segment waveform, i.e. defines the way
the switch over between the segments in a multi segment waveform will be execu-
ted:
●
In "Same Segment" mode, 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 the upon receiving of a trigger event.
Switching between the segments is triggered by changing the segment index in the
"Next Segment" field.
●
When "Next Segment" is selected, the current segment ceases to be output as
soon as a trigger event for a new segment occurs, and the new segment starts to
be output after a system-imposed signal gap.
The following figure shows an example of the transition from a sinewave signal
segment to a sawtooth segment (I channel, above) in the case of next segment
external triggering (below).
●
When "Next Segment" Seamless is selected and a new segment trigger event
occurs, the new segment is not output until the whole of the current segment has
