Note2: If Analog Base Gain is set at 0dB and Digital Gain is used at a high gain setting, the
video level may be unstable and may fluctuate approx. 5%. In this case, it is
suggested to set the analog base gain at +6dB or +12dB.
The above drawing shows the relationship between gain setting value (command), gain
amplitude, and dB indication. For example, the gain amplitude “x 0.44” equals -7dB.
