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