OPEN
Set picture mute to OFF (P-MODE: Normal 1, 000), brightness to maximum (11111111), color to center
(1000000), and unicolor to maximum (1111111).
Set SW68 to A. Set SW67 and SW66 to B, and input 100-kHz sine wave to TPA. Set #68 amplitude to
0.2 Vp-p.
3. Set SW74 open. Measure #74 amplitude VY00 and VY01 when Y/color difference input mode is set to
Y/Cb/Cr (0) and Y/Pb/Pr (1).
4. Set SW68 to C, SW67 to A, and SW66 to B. Input 100-kHz sine wave to TP67, and set #67 amplitude to
0.2 Vp-p.
5. Measure #14 amplitude VB00 when Y/color difference input mode is set to Y/Cb/Cr (0).
6. Measure #14 and #12 amplitude VBB01 and VBR01 when Y/color difference input mode is set to Y/Pb/Pr (1).
7. Set SW68 to C, SW67 to B, and SW66 to A. Input 100-kHz sine wave to TP66, and set #66 amplitude to
0.2 Vp-p.
8. Measure #12 amplitude VR00 when Y/color difference input mode is set to Y/Cb/Cr (0).
9. Measure #14 and #12 amplitude VRB01 and VRR01 when Y/color difference input mode is set to Y/Pb/Pr (1).
10. Calculate the following equations.
G_Y00 = 20 × log (VY00/0.2), G_Y01 = 20 × log (VY01/0.2)
G_CBB = 20 × log (VB00/0.2), G_PBB = 20 × log (VBB01/0.2),
G_PBR = 20 × log (VBR01/0.2)
G_CRR = 20 × log (VR00/02), G_PRB = 20 × log (VRB01/0.2),
G_PRR = 20 × log (VRR01/0.2)
