SG1 applied to TP33, TP35 and TP37.
SG10 applied to TP5, SG11 applied to
TP9, SG2 applied to TP11, define the
each amplitude (BLK-WHT) at
SW7=H, and TP31=0V, 2.5V,
5V as V1, V2 and V3.
Then measure the each output of the
non-inverting
GCT1=20LOG(V1/V2)
GCT2=20LOG(V3/V2)
Measure points are Rout, Gout, Bout.

SG3 (100KHz, 2.0MHz / 70mVp-p)
applied to TP28, SG10 applied to TP5,
SG11 applied to TP9, SG2 applied to
TP11, 1.5V applied to TP38, 3.2V
applied to TP39.measure amplitude on
TP2 of non-inverting. The each gain on
SG3 of sin signal of frequency define as
G(2.0M),G(100K).
GPSMIN1=G (2.0M)-G (100K)
At SW27=H, TP27=0V
GPSMAX1=G (2.0M)-G (100K)

applied to TP28, SG10 applied to TP5,
SG11 applied to TP9,SG2 applied to
TP11, 1.5V applied to TP38, 3.2V
applied to TP39.measure amplitude on
TP2 of non-inverting.The each gain on
SG3 of sin signal of frequency define as
G(2.0M),G (100K). (typical swing)
GPSMIN2=G (2.0M)-G (100K)

TP28.
B1, B2 define output swing of TP2
at TP19=2.8V,SG3 (3.579545MHz),
SG3 (100KHz). B3, B4 define output
swing of TP2 at TP19=0V, SG3
(4.43361875MHz), SG3 (100kHz).
