 Triggering during the Readout State 

o

 

For applications requiring the fastest triggering cycle time whereby the camera image sensor 
is exposing and reading out simultaneously, then the User Trigger signal should be applied as 
soon as a valid Trigger Ready is detected. 

o

 

In this case, Trigger Latency and Trigger Jitter can be up to 1 line time since Exposure must 
always begin on an Interline boundary.
