AKD PDMM User Guide | 13.2.2.4 Trigger Value
In the EWV scope, the 0 time point is clear. When collecting the data via REC.RETRIEVE or similar com-
mands, the time is not returned, so some caution should be used when the trigger point is important to
understand.
Trigger position is not used in trigger type “Immediate” (TRIGTYPE 0).
13.2.2.4 Trigger Value
The trigger value (REC.TRIGVAL) specifies a target value that should trigger the recording to start. The
trigger value is used in trigger type Parameter / On Next Signal only.
The trigger value is not used in the boolean trigger type. Use the trigger slope to set the polarity of the bool-
ean trigger.
When the trigger slope is positive, the trigger value will trigger when:
l
The trigger source is less than the trigger value in the previous recording sample
l
The trigger source is greater than or equal to the trigger value in the current recording sample
Below is an example showing triggering of trigger value of 3 (REC.TRIGVAL 3) and positive trigger slope
(REC.TRIGSLOPE 1). You can see that the recording triggers at time zero when the source reaches the
value of 3.
