Trigger Delay
The trigger delay is a programmable delay in milliseconds between the incoming trigger edge
and the start of the exposure. This feature may be required to synchronize to external strobe
with the exposure of the camera.
4.4.5
Burst Trigger
The camera includes a burst trigger engine. When enabled, it starts a predefined number of
acquisitions after one single trigger pulse. The time between two acquisitions and the number
of acquisitions can be configured by a user defined value via the camera software. The burst
trigger feature works only in the mode "Camera controlled Exposure Time".
The burst trigger signal can be configured to be active high or active low. When the frequency
of the incoming burst triggers is higher than the duration of the programmed burst sequence,
then some trigger pulses will be missed. A missed burst trigger counter counts these events.
This counter can be read out by the user.
