Trigger Overlap: Feature Details
The Trigger Overlap feature defines how the Nano 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 Nano model and sensor used.
• TriggerOverlap=Off
• No trigger overlap is permitted.
Diagram Conditions:
• TriggerMode=On
• ExposureMode=Timed
• TriggerActivation=RisingEdge
• TriggerDelay=0
