Conditions
Min.
Input SIG8 to (A). Adjust the non-inverted output
amplitude (black-white) at TP43 to 3.5Vp-p with serial 23.0
bus register CONT and the black level at TP43 to 1.5V
with serial bus register RBT.
Measure VG1, VG2 and VG3.

G γ 1 = 20 log (VG1/0.0375)
G γ 2 = 20 log (VG2/0.0375)
G γ 3 = 20 log (VG3/0.0375)
18.0
(See Fig. 5 for definitions of VG1, VG2 and VG3.)
Input SIG8 to (A) and adjust serial bus register
BRIGHT so that the output at TP43 is 9Vp-p (black-
black).
Read the point where the gain of the non-inverted
output at TP43 changes when serial bus register
γ 1 = 0 and 255 from the input signal IRE level.

∆VBLIM
Input SIG5 (VL = 0mV) to (A) and adjust BLKLIM so that
the output at TP43 is 9Vp-p (black-black). Measure the
