(See “White Side Gamma Measurement Method”.)

Set V45 = VI, V23 = 1.6V, V71 = 5.0V, V74 = 3.3V,

R gamma white side

170 breakpoint sub adjustment ∆PGWR1

range (1)

SW41 → ON and V41 = 1.6V.

Then measure the gamma breakpoint at TP16,

and label the non-inverted side as PGWGT and the

inverted side as PGWGTA.

— –0.3 –0.15 V

Next, measure the gamma breakpoint at TP15 with

SW75 → ON and V75 = 5.0, and label the non-

inverted side as PGWRN and the inverted side as

PGWRNA.

R gamma white side

171 breakpoint sub adjustment ∆PGWR2

range (2)

∆PGWR1 = PGWRN (A) – PGWGT (A)

Next, measure the gamma breakpoint at TP15 with

V75 = 1.6V, SW1 → ON and V1 = 2.3V, and label 0.15 0.3

the non-inverted side as PGWRM and the inverted

side as PGWRMA.

∆PGWR2 = PGWRM (A) – PGWGT (A)

(See “White Side Gamma Measurement Method”.)

B gamma white side

172 breakpoint sub adjustment ∆PGWB1

Set V45 = VI, V23 = 1.6V, V71 = 5.0V, V74 = 3.3V,

SW41 → ON, V41 = 1.6V, SW76 → ON and

V76 = 5.0V.

Then measure the gamma breakpoint at TP17,

and label the non-inverted side as PGWBN and the

inverted side as PGWBNA.

∆PGWB1 = PGWBN (A) – PGWGT (A)

B gamma white side

173 breakpoint sub adjustment ∆PGWB2

range (2)

Next, measure the gamma breakpoint at TP17 with

V75 = 1.6V, SW1 → ON and V1 = 2.3V, and set 0.15 0.3

∆VW2

Set V45 = 5.0V, V42 = 0V, V54 = 0V and input

SG1 (0dB) to (TEST IN).

Label the non-inverted output amplitudes (black to

white) at TP15, TP16 and TP17 as VWRLT, VWGLT 1.7 2.0 2.3 V

and VWBLT, and the inverted output amplitudes as

VWRLTA, VWGLTA and VWBLTA, respectively.

Next, label the non-inverted output amplitudes

(black to white) at TP15, TP16 and TP17 with

SW41 → ON and V41 = 5.0V as VWRLN, VWGLN

and VWBLN, and the inverted output amplitudes as

VWRLNA, VWGLNA and VWBLNA, respectively.

Next, label the non-inverted output amplitudes

(black to white) at TP15, TP16 and TP17 with

— –1.7 –1.3 V

V41 = 1.6V as VWRLM, VWGLM and VWBLM, and the

inverted output amplitudes as VWRLMA, VWGLMA

and VWBLMA, respectively.
