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. The analog
offset is factory calibrated and is applicable to exposure mode
sem 2/4
but no calibration is assumed for exposure mode
sem 3/7

The resulting analog offset value depends on other camera
parameters such as temperature, frame rate, and exposure
mode.
•
The upper input limit of the offset remains the same regardless
of the exposure mode.
