5.11. Pulse Width Trigger Shutter Mode
□
This is the mode to start exposure with external input trigger signals, and set the exposure time with
pulse width of the trigger signals.
□
The delay time
(Exposure Time Delay) from the detection of the trigger edge inside the camera
until the start of exposure is as follows.
(1) Trigger Hsync Mode ON : 1.70us + max1HD

・
2Tap Base Configuration Center Trimming 512(H)
max 1HD (3.225us)
(2) Trigger Hsync Mode OFF : 0.35us fixed
□
Pulse width is min. 2HD (min) to approx. 2 frames.
Functionally, there is no upper limitation, but noises such as dark noises and shadings may be noticeable
at long time exposure.
When the pulse width value is under 16.641us, the exposure time is up to 16.64us.
□
Triggers can be accepted even when outputting video signals.
However, trigger signals for exposure to start the next video output prior to the completion of video transmission
for the prior video output signals can not be accepted.
