5.4.2 Trigger Delay
This section serves to demonstrate the possible realization of a trigger delay setup in a user’s
application system.
For the purpose of clarity the example shown in Fig. 5.9 refers to a camera setup
with CameraLink interface and CameraLink frame grabber.
The total delay between the trigger edge and the camera exposure consists of the delay in the
frame grabber and the camera (Fig. 5.9). Usually, the delay in the frame grabber is relatively
large to avoid accidental triggers caused by voltage spikes (see Fig. 5.10). The trigger can also
be delayed by the property
Trigger.Delay .
