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
