(See "Black Side Gamma Measurement Method".)
Set V45 = V
1.6V.
Then obtain the gamma gain of the non-inverted
and inverted signals at TP15, TP16 and TP17.
(See "Black Side Gamma Measurement Method".)
Set V45 = V
1.6V.
Then label the non-inverted side gamma gain at
TP15, TP16 and TP17 as G
and the inverted side gamma gain as G
G
(See "Black Side Gamma Measurement Method".)
Set V45 = V
SW69
Then measure the gamma gain at TP15, and label
the non-inverted side as G
side as G
Next, measure the gamma gain at TP15 with
V69 = 5.0V, and label the non-inverted side as
G
(See "Black Side Gamma Measurement Method".)
Set V45 = V
SW70
Then measure the gamma gain at TP17, and label
the non-inverted side as G
side as G
Next, measure the gamma gain at TP17 with
V70 = 5.0V, and label the non-inverted side as
G
(See "White Side Gamma Measurement Method".)
Set V45 = V
1.6V, V71 = 1.6V and V74 = 5.0V.
Then measure the gamma gain of the non-inverted
and inverted sides at TP15, TP16 and TP17.
(See "White Side Gamma Measurement Method".)
Set V45 = V
1.6V, V71 = 5.0V and V74 = 5.0V.
Then measure the gamma gain of the non-inverted
