External Trigger Width Exposure
An alternative external trigger mode allows the external signal width to control the exposure
duration (feature ExposureMode = TriggerWidth), as illustrated in the following graphic.

Notes
•
In programmable exposure modes, the camera takes the additional exposure time into
account and matches the exposure time set by the user to the actual sensor exposure time.
The actual exposure time and the exposure time set by the user are the same.
•
In external trigger width exposure mode, the pulse is passed to the sensor. Therefore, the
actual exposure time is 1.6 µs longer than the exposure time determined by the trigger.
•
Concurrent integration and digital readout may occur, however, in the 4k only one row may
be read out at a time.
•
In case the trigger frequency exceeds the allowable line rate, the camera will buffer one
trigger.
