Figure 27: Trigger Control.
3.7.1 Trigger Options
The small Cheetah camera operates in free running mode or trigger mode. In free running
mode, the camera runs without synchronization. In trigger mode, the camera waits for
the trigger to start the image capture, synchronizing it to an external event.
To use triggers, select Trigger on the main menu. Use the following options to configure
the trigger source and other settings:
Trigger in
: Select one of the following active triggering input signals from the drop-down
list:
•
External 1. The camera expects a trigger signal coming from IN 1.
•
Pulse Gen. The camera expects a trigger signal coming from the internal pulse
generator.
•
Computer. The camera expects a signal coming from CC 1.
•
Software. Triggering starts when you click the software trigger button.
•
External 2. The camera expects a trigger signal coming from IN 2.
Mode
: Select a mode from the drop-down list:
•
Standard. The camera waits for the trigger, then exposes using the internal
exposure timer and reads out the frames. The exposure occurs first followed by
readout.
•
Fast. The camera exposes a frame and then exposes the next frame while reading
the previous frame. In this way, the camera overlaps the exposure and readout
times. Fast trigger requires a predictable and stable trigger period.
