Acquisition Frame Rate AcquisitionFrameRate Specifies the camera internal frame rate, in Hz.
Any user entered value is automatically adjusted to a
valid camera value. Note that a change in frame rate
takes effect only when the acquisition is stopped and
restarted.

Exposure Mode ExposureMode Sets the operation mode for the camera’s exposure
(or electronic shutter).
1.00
Beginner
Timed Timed The exposure duration time is set using the Exposure
Time feature and the exposure starts with a
FrameStart event.
Trigger Width TriggerWidth
Uses the width of the trigger signal pulse to control
the exposure duration. Use the Trigger Activation
feature to set the polarity of the trigger.
The Trigger Width setting is applicable with Trigger
Selector = Single Frame Trigger(Start). Note that the
Line Inverter feature setting may affect the polarity of
the trigger signal and is only available when
exposureAlignment = Reset.
Exposure Alignment exposureAlignment
Exposure Alignment specifies how the exposure is
executed in relationship to the sensor capabilities and
current frame trigger. 1.00
DFNC
Beginner
Synchronous Synchronous Exposure is synchronous to the internal timing of the
sensor. The readout is concurrent to the exposure for
the fastest possible frame rate. When a valid trigger is
received and the ExposureTime is shorter than the
readout period, the ExposureStart event is latched in
the previous frame’s readout. That is; the
ExposureStartEvent is delayed and is initiated when
the actual exposure starts such that the exposure
ends and readout begins as soon as the previous
readout has completed.
Reset Reset
Sensor timing is reset to initiate exposure when a
valid trigger is received. Readout is sequential to
exposure, reducing the maximum achievable frame
rates. That is, a trigger received during exposure or
readout is ignored since data would be lost by
performing a reset.
Exposure Delay (in μs) exposureDelay Specifies the exposure delay, in μs , to apply after the
FrameStart event before starting the ExposureStart
event.

Exposure Time (in μs) ExposureTime Sets the exposure time (in microseconds) when the
Exposure Mode feature is set to Timed. 1.00

Actual Exposure Time performed by sensor due to its
design, based on the requested Exposure Time. 1.00

Gain Selector GainSelector
Selects which gain is controlled when adjusting gain
features. 1.00
Beginner
Sensor Analog SensorAnalog
Apply an analog gain adjustment within the sensor to
the entire image.
Sensor Digital SensorDigital
Apply a digital gain adjustment within the sensor to
the entire image.
Digital DigitalAll Apply a digital gain adjustment to the entire image.
This independent gain factor is applied to the image
after the sensor.
Gain Gain
Sets the selected gain as an amplification factor
applied to the image. User adjusts the
Gain feature or
the GainRaw feature.

Raw Gain value that is set in camera
(model-specific for range and step values). 1.00
