12. Input the XGA FLAT FIELD 40 IRE to INPUT-A.
Adjust GAMMA/R GAIN, B GAIN so that the chroma-
ticity at this time (white) satisfies the specification.
Specification; 40 IRE (Xw ± 0.005, Yw ± 0.005)
13. Perform tracking adjustment so that both 80 IRE and 40
IRE satisfy the specification.
14. Input the XGA FLAT FIELD 20 IRE to INPUT-A.
Adjust GAMMA/R B1P, B B1P so that the chromaticity
at this time (white) satisfies the specification.
Specification; 20 IRE (Xw ± 0.005, Yw ± 0.005)
15. Memorize the adjustment value.
3-4-1-2. Text Mode Adjustment
1. Set γ MODE to Text.
2. Perform the following processes on the value adjusted
in the Graphics Mode (3-4-1-1) and copy the value.
GAMMA/GAIN:
Adjustment value in Graphics Mode +10 (Red)
Adjustment value in Graphics Mode +10 (Green)
Adjustment value in Graphics Mode +10 (Blue)
GAMMA/B1P:
Adjustment value in Graphics Mode (Both R/G/B)
GAMMA/B2P:
Adjustment value in Graphics Mode (Both R/G/B)
Switch γ MODE to Graphics.
Input the XGA Flat Field 50 IRE and measure the chro-
maticity (xg, yg) at this time.
Swichi γ MODE to Text and adjust yg 50 ± 4% GAMMA/
G GAIN to meet the specifications.
Input the XGA Flat Field 50 IRE and adjust GAMMA/
R GAIN, B GAIN (xg ± 0.005, yg ± 0.005) .
3. Memorize the adjustment value.
3-4-2. RGB W/B Low Mode Adjustment
1. Input the XGA signal to the INPUT-A.
2. Set γ MODE to Graphics.
3. The LOW MODE is set.
4. Perform the following processes on 3-3-1 adjustment
value.
R GAIN:Adjustment value in LOW Mode +5
G GAIN:Adjustment value in LOW Mode –5
B GAIN:Adjustment value in LOW Mode As it is
R BIAS:Adjustment value in LOW Mode As it is
G BIAS:Adjustment value in LOW Mode As it is
B BIAS:Adjustment value in LOW Mode As it is
5. Memorize the adjustment value.
