FUNCTIONS
The trigger acceptance prohibition period continues until all of CCD image has been transferred out of the camera.
When the transfer frame rate is reduced (3.75 fps of DFW-SX900, 7.5 fps of DFW-X700), data will continue to be transferred
even after readout of image has been completed as shown in the figure below. The trigger prohibition period continues until
data transfer ends.
All trigger inputs to the camera during the "Trigger Acceptance Prohibition Period" will be ignored.
The following equation is one method of roughly calculating the acceptable trigger interval.
Trigger interval = Exposure time + Frame rate
