(1) Input stepping signal whose amplitude is 0.3 V in video period to
pin 31 (Y IN) and pin 48 (Sync IN).
(2) Set bus data so that blanking and halftone are off.
(3) Connect power supply to pin 21 (Digital Ys). While impressing 0 V
to it, measure pedestal level of pin 13 output signal (G OUT)
(Vpl13).
(4) Connect power supply to pin 19 (Digital G IN) and impress it with 2
V.
(5) Raising supply voltage to pin 21 gradually from 0 V, measure video
level of pin 21 after output signal of pin 13 changed (Vlx13).
(6) From measurement results of the above steps 3 and 5, calculate
high level in the text mode.
Vmt13 = Vtx13 Vpt13
(7) Raising supply voltage to pin 21 further from that in the step 5,
measure level (Vtost) of pin 21 when the level of pin 13 output
signal changes from that in the step 5 to 6 dB as halftone data is
set to ON (the 6th step of Notes T30 to T34).
(8) In the condition of the above step 7, raise voltage impressed to pin
19 to 3 V and measure output voltage of pin 13 (Vos13).
(9) From results of the above steps 3 and 7, calculate high level of the
output in the OSD mode.
Vmos13 = Vos13 Vpt13
