Trigger Overlap: Feature Details
The Trigger Overlap feature defines how the Falcon4-CLHS handles triggers that might occur more
frequently than the Frame Active period (an exposure plus readout period). If
TriggerOverlap = Off, then triggers received before the end of the Frame Active period are ignored.
Other TriggerOverlap values are dependent on the camera model and sensor used.
TriggerOverlap = Off
 No trigger overlap is permitted.
Diagram Conditions:
 TriggerMode = On
 ExposureMode = Timed
 TriggerActivation = RisingEdge
 TriggerDelay = 0
 TriggerSelector = FrameStart
 ExposureAlignment = Synchronous
