The master gain control uses Digital Gain Control. All digital gain can be set by x0.01/step. If the
digital gain is set too high, a break in the Histogram may occur.
The above drawing shows the relation among gain setting value (command), gain amplitude,
and dB indication. For example, the gain amplitude “x 5.643” equals 15dB.
