52 ST-133 Controller Manual Version 3.B
Multiple Trigger
Multiple Trigger Kinetics mode takes a single image in the series for each External Sync
pulse received by the controller. Once the series is complete the shutter closes and
readout begins. Since the shutter is open during the entire series of images, if the External
Sync pulses are irregularly spaced then the exposures will be of different lengths. Once
the series has been read out the camera is ready for the next series. This timing is shown
in Figure 24, where a series of 6 frames is collected with 6 External Sync pulses.
