Setting Analog Offset
To set the analog offset of the camera, use the command:
Syntax:
sao t i
Syntax Elements:
t
Tap selection. Allowable range is 1 to 4, or 0 for all taps.
i
Analog offset value. Allowable range is 0 to 1023.
Notes:
 The offset increases linearly with higher values. A value of
100 does not equal an offset of 100DN.
 The resulting analog offset value depends on other camera
parameters such as temperature, line rate, and gain.
 The offset for calibrated and uncalibrated video is set and
saved separately.
Example:
sao 0 200
Subtracting Offset or Background
To subtract the video scene offset or any other background from the output video signal,
use the command:
Syntax:
ssb t i
Syntax Elements:
t
Tap selection. Allowable range is 1 to 4, or 0 for all taps.
i
Subtracted value in a range from 0 to 511.
Notes:
When subtracting a digital value from the digital video signal the
output can no longer reach its maximum. Use the ssg command
to correct for this. See section 3.13 Setting Gains for details on the
ssg command.
Example:
ssb 0 20
