SG6 (3.58MHz, 300mVpp) applied to

TP13, SG10 applied to TP5, SG2

applied to TP11, SG11 applied to

TP9. TP38=1.5V,TP39=3.0V,vary the

chroma phase on SG6, define the phase

at maximum output amplitude of TP48,

TP2, TP4 as ΘR,ΘG,ΘB.

ΘRB=ΘR-ΘB

ΘGB=ΘG-ΘB

SG6 (3.58MHz, 300mVpp) applied to

TP13, DC5V applied to TP5, SG2

Applied to TP11, SG11 applied to

TP4, adjust the chroma phase on SG6

for maximum the amplitude of TP4.

Measure the ratio of 7.159059MHz

component to the 15.734kHz component.
