applied to TP14, SG2 applied to

TP51,SG10 applied to TP41.

Define the phase causing the

maximum amplitude at TP13=1.6V

on TP46 as

Θ1. Define the each

phase causing the maximum

amplitude at TP13=2.8V,4.0V on

TP46 as

Θ2 and Θ3.

TP41,SG1(0.7Vpp) applied to

TP29,31,33, SG2 applied to SG2.

Then define the non-inverting side

of TP44, TP46, TP48 as VRB,

VGB, and VBB, the invert side of

them as VRBI, VGBI, and VBBI.

∆VBRGB=VRB-VGB,VBB-VGB

=VRBl-VGBl,VBBl-VGBl

SG4 applied to SW26=L,TP19,

define the non-inverting side of

TP44,TP46,TP48 as VRB(Y),

VGB(Y), and VBB(Y), the invert

side of

VRBI(Y), VGBI(Y), and

VBBI(Y).
