If T

For a Line Period of

Synchronisation Modes with Maximum Exposure Time
In these modes, the rising edge of the Trigger (internal or External) starts the readout process (T
pix
) of the previous integration.
The Real exposure time (Tint
real
) is finally equal to the Line Period (
T
per
) even if it’s delayed from (
T
x
+ T
d
) from the rising edge of
the incoming Line Trigger.
