2）. White Balance Adjustment (B)
General set-up:
Equipment Requirements: Color analyzer.
Input requirements:
For SZ factory:
Signal Type : RF signal
Set to PAL D/K system, frequency=184.25MHz ( for China
model ) with white pattern of 80%
Set to PAL B/G system, frequency=64.25MHz ( for AP
model ) with white pattern of 80%
Input Signal Strength : 10mV (80 dBuV) terminal voltage.
Input Injection Point : TV Tuner input
For FQ factory:
Signal Type : CVI (YPbPr)
Using Quantum Data Pattern Generator 802G or 802R or 882;
Set to 576i with white pattern of 80% (flat patten)
Alignment Request in the center of the screen
Apply full white pattern, select smart setting to be Standard. Adjusting SCALER GAIN R G B to reach
W/D and luminance in factory mode as below.
Adjust Color Temp in the factory Mode OSD by adjusting GAIN R xxx G xxx B xxx in
factory mode (Fig. 4)
CIE1391 chromaticity (x,y) shall be
Color Temp. x y

Warm
0.314 + 0.01 0.319 + 0.01
~ R/G/B Gain value <= 127 to avoid satsuation at 32-grey pattern.
~At TV Luminance at Normal >= 250 cd/m

when contrast and brightness and color are 100%.
~At PC Luminance at Normal >= 250 cd/m
2
when contrast and brightness are 100%.
~
These group settings about color temp are also applied automatically into
HDMI1/CVI(for SZ factory)/SIDE AV/PC/TV(for FQ factory). That means TV/HDMI/CVI/PC are
used the same setting.
