Note2: If Analog Base Gain is set at 0dB and Digital Gain is used at high gain setting, the
video level may be unstable and fluctuating approx. 5%. In this case, it is suggested
to set the analog base gain at +6dB or +12dB.
The above drawing shows the relation among gain setting value (command), gain amplitude,
and dB indication. For example, the gain amplitude “x 3.16” equals 10dB.
