VA GigE series
Trigger Width Exposure Mode
When the Trigger Width exposure mode is selected, the length of the exposure for each frame acquisition will
be directly controlled by the external trigger signal. If the camera is set for rising edge triggering, the exposure
time begins when the external trigger signal rises and continues until the external trigger signal falls. If the
camera is set for falling edge triggering, the exposure time begins when the external trigger signal falls and
continues until the external trigger signal rises. Figure8.5 illustrates Trigger Width exposure with the camera set
for rising edge triggering.
Trigger Width exposure is especially useful if you intend to vary the length of the exposure time for each frame.
