Related Setting Items:
The following three gain functions are available on the camera: Sensor Conversion Gain, Analog
Base Gain, and Analog Fine Gain.
Sensor Conversion Gain
Sensor conversion gain (SCG) is InGaAs sensors' internal gain. Settings configured individually
from an external source, and the amount of gain can be adjusted via different combinations of 3-
bit setting values.

Analog Base Bain
Analog base gain (ABG) is gain that is performed prior to the video signal output from the sensor
passing through the CDS circuit. Settings can be configured individually from an external source.
The gain steps can be configured to one of four levels.
When the gain level is low, the video output may not be saturated in some cases. Therefore,
check whether the video is saturated whenever you change the settings.
