Setting Analog Offset
Purpose: Sets the analog offset. The analog offset should be set so that it is
at least 3 times the rms noise value at the current gain. DALSA
configures the analog offset for the noise at the maximum
specified gain and as a result you should not need to adjust the
analog offset.
Syntax:
sao t i
Syntax Elements:
t
Tap selection. Use
0
for all taps or
1
to
8
for individual tap
selection.
i
Offset value in a range from
0
to
255
DN (12 bit LSB).
Notes: •
To return the current analog offset value, use the command
gcp
or
get sao
.
Example:
sao 3 35

Calibrating Analog Offset
Purpose: Instead of manually setting the analog offset to a specific value,
the camera can determine appropriate offset values. This
command calculates and averages each tap’s pixels within the
region of interest and sets the offset to achieve the specified
average target value.
Syntax:
cao t i
Syntax Elements:
t
Tap selection. Use
0
for all taps or
1
to
8
for individual tap
selection.
i
Average target value in a range from
0
to
255
DN (12 bit
LSB).
Notes: •
Perform analog offset calibration before performing FPN and
PRNU coefficients.
•
To return the current analog offset values, use the command
gcp
or
get cao
.
Example:
cao 1 50
