This is the Gate output.

This is the AUX output.
In LightField, the number of on-CCD accumulations was set to 3. The Camera Timing
Dashboard will now look like that illustrated in Figure E-1.

In order to use the AUX pulse also, enable it in the Trigger Out expander or in the
Camera Timing Dashboard. The Camera Timing Dashboard will now look like that
illustrated in Figure E-2.
Figure E-2: AUX Pulse
Adjust widths and delays by entering values in the appropriate windows, or using the
spinners. The above screens show the internal trigger, readout per trigger mode.
Internal trigger selects the trigger from the camera and a complete pulse set is
generated, then the control is returned to the camera for readout.
E.2.2 Sequential Timing Mode
Sequential Mode is used to create a sequence of pulse sets that change linearly from
frame to frame. Figure E-3 is an example of sequential operation with 3 frames in the
sequence and 3 pulses in each frame. LightField displays the first and last sequence. The
trigger can be either internal or external. If you select external trigger, you can have
each external trigger start one pulse (Gate per Trigger) or each trigger start the set of
pulses per frame (in this example 3 gates/frame) or have a single external trigger start
the whole sequence of gates and readouts (Start on Single Trigger). If you select internal
trigger, the selections are limited to Readout per Trigger and Gate per Trigger. Gate per
Trigger provides only one gate, even when more have been selected.
