In trigger mode, the maximum frame rate is lower than in freerun mode because the sensors
expose and transfer sequentially. The possible frame rate in trigger mode depends on the
exposure time.
Example: At the maximum exposure time, the frame rate is about half as high as in freerun mode;
at the minimum exposure time, the frame rate is about the same.
