9.7.5 Set Trigger Debouncer

The trigger debouncer function allows the device to filter out unwanted short external

trigger signal that is input to the device.

Go to Digital IO Control → Line Debouncer Time, and enter Line Debouncer Time

according to actual demands. The range of Line Debouncer Time is from 0 μs to 1000000

μs.

Note

If the Line Debouncer Time you set is greater than the time of trigger signal, this trigger

signal will be ignored.
