delay is inevitable.
As a result, the camera cannot start exposure before the internal trigger delay time
has expired. An optical pulse that is received during this time span (t
Delay
)cannot be

The internal trigger delay t
Delay
depends on the selected exposure time:
When entering a desired delay to the box ‘Target Delay’, the software displays the
resulting ‘Actual Delay’ as the closest possible value.
Example for exposure time = 0.020ms (20µs):
