Assume the TP10 output when SG4
(0.1Vp-p) is input to TP23 as RR,
the TP8 amplitude when SG4
(0.1Vp-p) is input to TP24 as BB,
the TP10 amplitude when SG5
(0.1Vp-p) is input to TP23 as RG,
and the TP8 amplitude when SG5
(0.1Vp-p) is input to TP24 as BG.
B-Y/R-Y = RR/BB
G-Y/R-Y = RG/RR
G-Y/B-Y = BG/BB
Input SG3 to TP22 and measure the
frequency which results in –3dB
relative to the TP12 amplitude at
100kHz when LPF = 01h and 07h.
Set U-BRT = 30h, CONT = DFh,
input SG7 (13.5MHz) to TP22, TP23
and TP24, and measure the amount
by which each output is attenuated
relative to SG7 (100kHz).
Set SW8, SW10 and SW12 = ON,
input SG3 to TP22, TP23 and TP24,
and measure the frequency which
results in –3dB relative to the TP8,
TP10 and TP12 amplitude at 100kHz.
Measure the REF pin output voltage
at the output current 1.5mA sink.
Measure the DA
output voltage when
DA = 00h and 07h.
Input SG2 (0.35mVp-p) to TP22 and
measure the amplitude at TP8, TP10
and TP12.
Assume the output amplitude when
GAMMA1 = 7Fh as V1, when
GAMMA1 = 3Fh as V2, and when
GAMMA1 = GAMMA2 = 3Fh as V3.
Input SG2 (0.35mVp-p) to TP22 and
read the gain transition points of the
non-inverted output at TP12 when
level of the input signal.
1 = 00h and 1 = 7Fh from the IRE
1 = 00h: V
1 = 7Fh: V
1 = 20 log (V1/V2)
2 = 20 log (V3/V2)
