5.6.11 Hold Off
In trigger inhibition, hold represents inhibition and off represents release. Trigger hold-off can be
used for other trigger modes other than Free run mode. Intuitively, trigger hold-off can be
understood as the strictening of trigger conditions, that is, the occurrence of a trigger must not only
satisfy the trigger condition of the selected trigger, but also satisfy the additional conditions in
trigger hold-off.
Normal
In normal mode, the count is performed before the trigger, and the next trigger can only be
generated after the count meets the set requirements.
Above
For the rising edge of the video trigger (external trigger), it is required that after the trigger, the
actual level is still higher than the trigger level (trigger threshold) for at least a specified time.
For the falling edge of video trigger (external trigger), it is required that the actual level is higher
than the trigger level (trigger threshold) for a single accumulation time exceeding the specified
time before triggering.
For the periodic trigger, the trigger moment is high level, the duration is a time period, and the
other time is low level, which can be inferred according to other triggers.
Below
For the rising edge of video trigger (external trigger), it is required that the actual level is lower than
the trigger level (trigger threshold) for a single accumulation time exceeding the specified time
before triggering.
For the falling edge of the video trigger (external trigger), it is required that the actual level is still
lower than the trigger level (trigger threshold) after triggering for at least a specified time.
The periodic trigger can be pushed in the same way.
