The camera has a factory calibrated analog gain setting. Adjustment of analog gain is not
available to the user, however, digital gain is available using the set system gain serial

ssg
.
4.10.2
Setting Digital System Gain
Serial Command
Purpose:
1)
Increases the overall gain of the camera.
2)
Improves signal output swing after a background
subtract. When subtracting a digital value from the
digital video signal, using the
ssb
command, the output
can no longer reach its maximum. Use this command to
correct for this where:
ssg value =
max output value
max output value - ssb value
Syntax:
ssg
t i
Syntax Elements:
t
Sensor tap selection. This is always
0
for all taps.
i
Gain setting. The gain ranges are
1024
to
8191
. The digital
video values are multiplied by this value where:
Digital Gain =
1024
i
For example, to set a digital gain of 2.0,
i
equals 2048.
Notes:
•
Entering a large value gain will cause the camera to digitally
saturate the output image
Example:
ssg 0 1024
