Trigger timings
This section will detail the timings related with the trigger. There are few timings that must be kept in
mind when using the triggers. They are shown below:
Sensor effective exposition datagram
Please note, that when the sensor uses a trigger, the exposition has a delay before the start of the
exposition, and another delay before the end of the exposition.
The dead time is the minimum time between a TriggerEnd and a following TriggerStart. It is depending
on the post exposition delay, and the memory wait time. The memory wait time cannot be outputted
from the sensor.
The TriggerEnd must not occur before a full sensor readout.
The sensor data output delay is the latency between TriggerEnd and sensor readout.
In addition to the delay, a jitter is present when integration starts. This jitter comes from the sampling
of the input trigger signal which is aligned to line multiple. The same jitter is present at the end of
integration if the trigger mode used drives the integration time too.
