Also known as “Pulse Width Control” exposure. See the timing diagram below.

The external trigger edge initiates the exposure process. The active external trigger edge can be selected as
either the low-high or high-low transition.

No delay from active trigger edge to start of exposure. Note that the user must account for the input opto-
coupler electrical specifications (see
" External Inputs " on page 109 ).

Exposure is stopped by the opposite edge on the trigger signal. Therefore the exposure time is defined by the
trigger pulse duration.

Supports " Reset Mode " on page 52 trigger timing only.
