exposure time is the time between external triggers and hence the user cannot set the exposure or cycle times.
However, the user can dene the amount of time between the external trigger event occurring and the readout
starting. This can be useful in those situations where the TTL trigger occurs before the light event you are trying
to capture. This effectively moves the exposure window in time but the exposure time is still the period between
trigger events.
