4.5.3 External Trigger (TriggerWidth) Exposure Mode
The external trigger (Trigger
Width) exposure mode can be used when ”On” (Enable)
on “Trigger Mode” and “Trigger Width” on “Exposure Mode” are set.
The line period is determined by the time from rising edge to rising edge of the trigger
pulse cycle. The start of each exposure is determined by the rising edge of the
trigger pulse cycle. The exposure time is set by the trigger pulse H time.
The range of the settable line period is shown below.
