Set SW39
V25 = 1.6V. Then label the non-inverted reference
level potential at TP15 as V
reference level potential as V
Next, label the non-inverted reference level potential
at TP15 with V25 = 5.0V as V
reference level potential as V
Set SW39
V24 = 1.6V. Then label the non-inverted reference
level potential at TP17 as V
reference level potential as V
Next, label the non-inverted reference level potential
at TP17 with V24 = 5.0V as V
reference level potential as V
Set V45 = V
SG1 (0dB) to (R IN), (G IN) and (B IN).
Then label the non-inverted output amplitudes (black
to white) at TP15, TP16 and TP17 as V
and V
V
Set V45 = V
Then label the non-inverted output signal reference
level amplitudes at TP15, TP16 and TP17 as V
and V
amplitudes as V
V
(See “Black Side Gamma Measurement Method”.)
Set V45 = V
Then measure the minimum gain GN of the non-
inverted and inverted signals at TP15, TP16 and TP17.
G
(See “Black Side Gamma Measurement Method”.)
Set V45 = VI, V23 = 1.6V and V77 = 1.6V.
Then obtain the gamma gain of the non-inverted and
inverted signals at TP15, TP16 and TP17.
