TEST CONDITIONS (DEF V_CC = 9 V, Ta = 25 ± 3°C, BUS DATA = POWER-ON RESET)
MEASUREMENT METHOD
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_CC.)

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_HO (15.7 kHz ± 1 kHz).
(Apply only DEF V_CC.)
B
1) Under the above conditions, when no horizontal pulse is output on #35, read D₄ in bus read mode. (Apply
also the chroma V_CC.) (V_{BUS HOFF})
2) Under the above conditions, when a horizontal pulse is output on #35, read D₄ in bus read mode. (Apply
also the chroma V_CC.) (V_{BUS HON})
Observe the #35 (H out) waveform and measure t1 and t2.

B
Input a composite video signal to TP38. When the subaddress (0D) D₁ is set to (1), measure the oscillation frequency of the #35 (H out)
waveform.
B ^{Measure the oscillation frequency of #35 (H out).}
1) When #40 (AFC1 FILTER) is connected to DEF V_CC via a 10-kΩ resistor, measure the #35 (H out) oscillation frequency. (V_HMIN)
B
2) When #40 (AFC1 FILTER) is connected to GND via a 68-kΩ resistor, measure the #35 (H out) oscillation frequency. (V_HMAX)
B
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.
