Trigger-first mode In this mode, the camera requires only one trigger to acquire a sequence of
frames. Each frame is exposed for a length of time entered into the software
and read out. Once the trigger is received, the camera is inhibited from taking
any further triggers until the entire sequence is completed (see Figure 4).

Strobe mode In this mode, each frame in a sequence requires a trigger. Each frame is
exposed for a length of time entered into the software and is then read out. If
the trigger arrives during the exposure-readout of the previous frame, it is
ignored (see Figure 5). For a sequence of one frame, strobe mode and trigger-
first mode are the same.
