3.1. ADC Process

(1) PC input ADC

1) Auto RGB Gain/Offset Adjustment

- Convert to PC in Input-source

- Signal equipment displays

Output Voltage : 700 mVp-p

Impress Resolution XGA (1024 x 768 @ 60Hz)

Model : 60 in Pattern Generator

Pattern : 65 in Pattern Generator (MSPG-925 Series)

- Adjust by commanding AUTO_COLOR_ADJUST.

2) Confirmation

- We confirm whether “0xAA (RGB)” address of

EEPROM “0xA2” is “0xAA” or not.

- If “0xAA (RGB)” address of EEPROM “0xA2” isn’t

“0xAA”, we adjust once more

- We can confirm the ADC values from “0xA4~0XA9

(RGB)” addresses in a page “0xA2”

* Manual ADC process using Service Remocon. After

enter Service Mode by pushing “ADJ” key,

execute “ADC Adjust” by pushing “

G” key at “ADC

CALIBRATION: RGB-PC”.

(2) COMPONENT input ADC

1) Component Gain/Offset Adjustment

- Convert to Component in Input-source

- Signal equipment displays

Pattern : 65 in Pattern Generator (MSPG-925 series)

Impress Resolution 1080i

Model : 223 in Pattern Generator(1080i Mode)

Pattern: 65 in Pattern Generator(MSPG-925 series)

- Adjust by commanding AUTO_COLOR_ADJUST.

2) Confirmation

- We confirm whether “0xB3 (480i)/0xBC (1080i)”

address of EEPROM “0xA2” is “0xAA” or not.

- If “0xB3 (480i)/0xBC(1080i)” address of EEPROM

“0xA2” isn’t “0xAA”, we adjust once more.

- We can confirm the ADC values from “0xAD~0XB2

(480i)/0XB6~BB (1080i)” addresses in a page “0xA2”.

* Manual ADC process using Service Remocon. After

enter Service Mode by pushing “ADJ” key, execute

“ADC Adjust” by pushing “

G ” key at “ADC

CALIBRATION :COMPONENT”.
