. ADJUSTMENT
10. AGC level adjust : AGC (Automatic Gain Control)
This circuit reduces intermodulation and prevents saturation occurring at the amplification stage of
the AF sensor. For example, if the input value is greater than the standard value in the AF
amplification circuit, this circuit reduces the gain. If the input value is smaller than the standard value,
this circuit increases the gain for better output.
Auto Gain Control
If the signal is stronger than the standard, saturation of the signal is prevented by controlling the gain
(similar to sensitivity of film). If the signal is weaker than the standard, it increases the level of the
signal up to the standard.
1. Adjustment procedure
✁
Install a 50mm F1.4 lens on the camera. (Set the focus mode to MF.)
