Selects how to combine the rows for
processing.
TdiOff A single sensor row is output per line trigger.
Multiple sensor rows are synchronized and
TdiSum
summed together in the camera to increase the
camera responsivity.
TdiAvg Multiple sensor rows are synchronized and
averaged together in the camera to increase
the signal to noise ratio.
Multiple sensor rows with independent
TdiHdr
exposure times are synchronized and combined
together. This mode can be used to produce a
high dynamic range demonstration image with
enhanced contrast in dark image regions.
TdiMultiLine Two sensor rows are synchronized and output
per input line trigger. This enables processing
of the synchronized image rows by the host
system. The output image frame will consist of
alternating sensor rows starting with row one.
Selects the number of rows to sum / average in
TDI.
Row1 Single row.
Rows2 Two rows summed / averaged together.
Sets the number of lines of delay between two
sensor lines from the sensor for Spatial
Correction. Stop acquisition to change. Possible
values are device-dependent; for example, for
certain m odels a numerical value is specified.
On Turn on spatial correction.
Off Turn off spatial correction.
Specifies the camera internal line rate, in Hz.
Actual sensor line rate output.
Sets the operation m ode for the camera's
exposure.
Timed The exposure duration time is set using the
Exposure Time
with a LineStart event.
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
when the LineStart trigger is enabled and a
signal is selected as trigger source.
Specifies the delay, in µs, to apply after the
LineStart event before starting the
ExposureStart event. Available when Exposure
Mode is Tim ed.
Sets the exposure delay for the second sensor
row. This feature is available for 4k cameras.
Delay050 Delay by 50% of previous exposure.
Delay15 Delay exposure by 15 μs.
Sets the exposure time , in µs, when the
Exposure Mode feature is set to Tim ed.
Exposure time applies to all channels.
