6.1.2 Input Line Debouncers
The debouncer feature aids in discriminating between valid and invalid input signals and only lets
valid signals pass to the camera. The debouncer value specifies the minimum time that an input
signal must remain high or remain low in order to be considered a valid input signal.
Note that the debouncer delays a valid signal between its arrival at the camera and its transfer. The
duration of the delay will be determined by the debouncer value.
Default value: 10 µs
Figure 16 illustrates how the debouncer filters out invalid input signals, i.e. signals that are shorter
than the debouncer value. The diagram also illustrates how the debouncer delays a valid signal.
By default, input line 1 is selected as the source signal for the frame start
trigger and input line 2 is selected as the source signal for the acquisition start
trigger.
We recommend setting the debouncer value so that it is slightly greater than the
longest expected duration of an invalid signal.
Setting the debouncer to a value
that is too short will result in accepting invalid signals.
that is too long will result in rejecting valid signals.
