AVIIVA® EM4 BA8
Ext Trig with Exposure time set in the camera
This mode requires an external trigger ( via CC1) but the exposure time is the one defined in the Camera.
If the line period of the Trig signal provided to the camera is lower than the exposure time set in
the camera, the “short trig pulses” will be ignored : The exposure set in the camera defines the
minimum line period possible.

Ext Trig Full Exposure time available
This mode requires an external trigger ( via CC1). The exposure time is the maximum possible value
between two Tri pulses.
In this mode, the exposure time set in the camera is ignored.
Avoid this mode if your trigger is not stable (variable line period) : The exposure of each line could
then be different. If the period of the trig signal is less than the readout time, the Camera won’t
send any signal.
