Adjustment address 1F9
Adjustment level 300mVp-p
1) Measure the burst signal level on the oscilloscope. Using the
address 1F9, adjust the burst amplitude to 300mVp-p.
4. Data processing after adjusting the black balance
1) 5 digit subtraction from ROB adjustment data at AGC MIN (address 19Ch) = (address 19ch) - 5h
5 digit subtraction from ROB adjustment data at AGC MAX (address 19Dh) = (address 19Dh) - 5h
5 digit subtraction from ROB adjustment data at GAIN UP (address 19Eh) = (address 19Eh) - 5h
