3.5.3.3 - External Start (FK)
External Start trigger mode is a combination of External and Internal Trigger. At the start of the capture process, the
camera is running the External Keep Clean Cycle waiting for a trigger pulse to be applied to the External Trigger input.
On receiving the trigger the exposure starts. The exposure period is dened by the user. On completion of the exposure
period, the camera performs the number of vertical shifts dened by the sub-area height (set by the user) and, then
again, waits for the exposure period before the next set of vertical shifts. This process is repeated until the number in the
series has been captured at which point the readout starts.
