10.10Manual Gain Control
What can be done ?
Beside the AGC there is the possibility to manually set the gain of the incoming video signal. When the AGC is enabled (ON), the
manual setting does not affect the gain, AGC must therefore be disabled. The manual gain control must be done on an external
pattern with white areas (grey scale bar pattern)
