TRIGGERING
SDK SECTION 5
Page 53
External Start
In External Start Trigger Mode, once an acquisition has been started via the
StartAcquisition function, the
camera system is placed into an external keep clean mode, which ensures that the CCD is not saturated
before the external trigger occurs. Once the External Trigger is received, the Keep Clean sequence is
stopped and the acquisition is initiated. After the initial acquisition the system will then continue to operate as
in internal trigger mode. The figure below illustrates the timing sequence for this mode of operation.
