able
(1) Set the bus data so that picture quality control frequency is 2.5 MHz.
(2) Input TG7 sine wave (sweeper) signal whose video level is 0.1 V to pin 45 (Y1 IN)
and pin 51 (Sync. IN).
(3) Maximize the picture quality control data.
(4) While observing Y1out of pin 37, find an SG frequency as the waveform amplitude
is maximum (fp25).
(5) Set the bus data so that picture quality control frequency is 3.1 MHz and 4.2 MHz,
and perform the same measurement as the above steps 2 through 4 at the
respective frequencies (fp31, fp42).

(1) Input TG7 sine wave (sweeper) signal whose video level is 0.1 V to pin 45 (Y1 IN)
and pin 48 (Sync. IN).
(2) Set the picture quality control data to maximum.
(3) Set the picture quality control frequency is 2.5 MHz by setting the bus data.
(4) Measure amplitude (V100k) of the output of pin 37 (Y1 OUT) as the SG frequency
is 100 kHz, and the amplitude (Vp25) of the same as the SG frequency is 2.5 MHz.
GS25MX = 20 og (Vp25 / V100k)
(5) Set the picture quality control frequency data to 3.1 MHz by setting the bus data.
(6) Measure amplitude (V100k) of the output of pin 37 (Y1 OUT) as the SG frequency
is 100 kHz, and the amplitude (Vp31) of the same as the SG frequency is 3.1 MHz.
GS31MX = 20 og (Vp31 / V100k)
(7) Set the picture quality control frequency to 4.2 MHz by setting the bus data.
(8) Measure amplitude (V100k) of the output of pin 37 (Y1 OUT) as the SG frequency
is 100 kHz, and the amplitude (Vp42) of the same as the SG frequency is 4.2 MHz.
GS42MX = 20 og (Vp42 / V100k)
