8.5.3 Pulse Width Control Trigger Mode (PWC)
In this mode the accumulation time is equal to the trigger pulse width. Here it is possible to
have a long time exposure. The maximum recommended time is <2 seconds however,
depending on your application, slightly longer exposure may still produce an acceptable
signal-to-noise ratio.
The accumulation can be LVAL asynchronous only.
The resulting video signal will start to be read out after the trigger rising edge.
For timing details, refer to fig. 21.through fig.26, fig.28.
To use this mode:
Set function: Trigger mode
