The minimum trigger period is equal to the maximum exposure time plus the camera readout
time:
Trigger Period (min) = Exposure Time (max) + Readout Time,
where the Readout Time is equal to the
CurrentFrameTime
(in free-running mode, with
AcquisitionFrameRateEnable
disabled).
If the next trigger pulse appears during the previous trigger period, the camera ignores it.
