(4) Pulse width trigger mode
In this trigger mode, shutter speed is set by the trigger pulse width.
The trigger pulse width must be set within 1H to 1/2 sec.
1HD step fine shutter speed setting is available.
The following formula can be used to calculate approximate exposure time.
exposure time
=
trigger pulse width (nHD) + 13.338us
( HD = 26.67us )
Be sure to input HD sync signal, otherwise both 1HD of exposure starting point and the exposure time
will
be fluctuated by 1HD if a jitter occurs between trigger input and internal sync.
