pulse width of the external trigger, which is similar to PWC mode. The real exposure time of the first
image is equal to the pulse width of the external trigger.
pulse width of the external trigger, which is similar to PWC mode. The real exposure time of the first
image is equal to the pulse width of the external trigger.
The maximum trigger frequency in this mode is equal to 1/ (transfer time of two frames + exposure time
