This finely adjusts the VCO oscillation center frequency. Adjustment from LSB
frequency.
Perform this adjustment after adjusting VCO-Coarse.
This roughly adjusts the VCO oscillation center frequency. Adjustment from LSB
frequency.
Adjust with VCO-Fine set to 10000000 (LSB).
This adjusts the black side limiter level of the RGB output signals. Adjustment from LSB
limiter level.
This adjusts the picture gain during Y/color difference input. Adjustment from LSB
When not using the picture function, set PICTURE-GAIN: 00000 (LSB).
This sets the picture center frequency (f0) during Y/color difference input. See the AC Characteristics for the
output level.
This switches the frequency response of the low-pass filter. Set the fc/–3dB frequency relative to the
amplitude 100kHz reference. See the AC Characteristics for the output level.
