External Trigger Exposure Mode (Trigger Level)
In external trigger exposure mode
(Trigger Level)
, the exposure time is
determined by the setting for the line period parameter, each exposure starts
with the rising edge and the line period is determined by high trigger pulse
time. The range of programmable exposure time, the timing chart of the
exposure and the readout are shown below.
