The section comprises the settings necessary to adjust the trigger for the switch between
the segments of a multi segment waveform. The parameters displayed depend on the
selected trigger source.
Current Segment
Indication of the waveform segment (segment file name and index) that is currently out-
put.
SCPI command:
[:SOURce<hw>]:BB:ARB:WSEGment on page 615
[:SOURce<hw>]:BB:ARB:WSEGment:NAME on page 618
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 Segment"
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
Next Segment Mode.
The segment currently being output (segment index and file name) is displayed at "Cur-
rent Segment". The subsequent trigger event after the last segment causes the first seg-
ment to be output again.
SCPI command:
[:SOURce<hw>]:BB:ARB:WSEGment:NEXT on page 618
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 executed:
●
In "Same Segment" mode, the processing of the multi segment waveform file is sim-
ilar to the processing of a non-multi segment waveform, i.e. there is no switching to
consequtive segment the upon receiving of a trigger event.
Switching between the segments is triggerd 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 seg-
ment to a sawtooth segment (I channel, above) in the case of next segment external
triggering (below).
