Note
The exposure time step width is limited to the sensor's row time of 4.86 us and therefore
- auto exposure with very low exposure times will perform with relatively large increments and
- exposure mode = TriggerWidth (if available) will perform with a jitter corresponding to the row time
The following trigger modes are available:
Setting (GenICam) Mode / Setting (obsolete "Device
Specific")
Description
"TriggerSelector =
FrameStart"
"TriggerMode = Off"
Continuous Free running, no external trigger
signal needed.
"TriggerSelector =
FrameStart"
"TriggerMode = On"
"TriggerSource =
Software"
"ExposureMode = Timed"
To trigger one frame execute
the TriggerSoftware@i command
then.
OnDemand Image acquisition triggered by
command (software trigger).
"TriggerSelector =
AcquisitionActive"
"TriggerMode = On"
"TriggerSource =
<desired Line>"
"TriggerActivation =
LevelLow"
"ExposureMode = Timed"
OnLowLevel Start an exposure of a frame as
long as the trigger input is below
the trigger threshold. (No Frame←-
Trigger!)
"TriggerSelector =
AcquisitionActive"
"TriggerMode = On"
"TriggerSource =
<desired Line>"
"TriggerActivation =
LevelHigh"
"ExposureMode = Timed"
OnHighLevel Start an exposure of a frame as
long as the trigger input is above
the trigger threshold. (No Frame←-
Trigger!)
"TriggerSelector =
FrameStart"
"TriggerMode = On"
"TriggerSource =
<desired Line>"
"TriggerActivation =
FallingEdge"
"ExposureMode = Timed"
OnFallingEdge Each falling edge of trigger signal
acquires one image.
"TriggerSelector =
FrameStart"
"TriggerMode = On"
"TriggerSource =
<desired Line>"
"TriggerActivation =
RisingEdge"
"ExposureMode = Timed"
OnRisingEdge Each rising edge of trigger signal
acquires one image.
