waveform.
Measure the oscillation frequency of #35 (H out).
1) When #40 (AFC1 FILTER) is connected to DEF V
2) When #40 (AFC1 FILTER) is connected to GND via a 68-kΩ resistor, measure the #35 (H out) oscillation frequency. (V
When the voltage on #40 (AFC1 FILTER) is varied by ±0.05 V with a horizontal oscillation frequency of 15.734 kHz, calculate the #35 (H
out) frequency variation rate.
TEST CONDITIONS (DEF V
Increase the voltage from 2.5 V.
When an oscillation waveform appears on TP41, measure the voltage. At the same time, check that no
waveform is output (0V DC) to #35 (H out).(Apply only DEF V
Increase the voltage. When a horizontal pulse appears on #35 (H out), measure the voltage. Note that the
horizontal oscillation frequency at this time is near f
(Apply only DEF V
1) Under the above conditions, when no horizontal pulse is output on #35, read D
2) Under the above conditions, when a horizontal pulse is output on #35, read D
