Figure 5-28: Principle of segment triggering
*
= To simplify the description, an internal next segment trigger event ("Exec. Next Segment") and an
internal trigger event ("Execute Trigger") are used; an external trigger event has the same effect on
the signal generation.
1, 2 = Any next segment trigger event (internal or external) causes a switch over to the subsequent available
segment in the waveform. The currently output segment (segment file name and segment index) is
indicated at "Current Segment".
3
= When the last segment of the multi segment waveform has been output, the sequence starts again
with the output of the first segment after the subsequent trigger event. Hence, a sequence of external
next segment trigger events can be used to cyclically output the segments in the multi segment file.
Defining Next Segment Source
As with the standard trigger system, provided are the following two sources for the next
segment signal:
●
Internal
: the switch over to the subsequent segment is triggered manually by
means of the "Execute Next Segment" function.
To trigger a switch over to any segment within the multi segment waveform,
change the value of the "Next Segment".
●
External
: the instrument expects an external trigger event (signal at the corre-
sponding connector)
Defining the Subsequent Segment
By default, the instrument replays the segments in incremental order, e.g. Segment#1,
Segment#2, etc. If other order is required, use one of the following possibilities to
define the segment to be played next:
●
Next Segment
: defines the subsequent segment while triggering the segments
manually, i.e. by "Next Segment Source > Internal"
●
Sequencing List
: the subsequent segment is defined in the selected play list.
