TEST CONDITIONS (DEF VCC = 9 V, Ta = 25 ± 3°C, BUS DATA = POWER-ON RESET)
MEASUREMENT METHOD
Decrease the amplitude of #34 (FBP in) from 9 Vp-p.
When AFC2 stops locking, measure the amplitude.
(VHBLK1)
Increase the amplitude of #34 (FBP in) from 0 Vp-p.
When horizontal blanking is applied to #13 (R in),
measure the amplitude. (VHBLK2)
Input a signal as shown below to TP38 from TG7. When the voltage is varied from 3 V to 6 V, measure the
phase variation in the #34 (FBP in) waveform.

Set the subaddress (01) D7 to (0), set the subaddress
(05) D3~D1 to (010), and set the subaddress (0C) D0 to
(1).
When a signal as shown at left is input to TP38 from TG7,
measure the #32 (HD out) waveform phase difference
HBPS and pulse width HBPW in relation to the #40 (AFC1
FILTER) waveform.
Set the subaddress (02) D7 to (1).
Increase the voltage from 0 V. When #52 reaches 3.4 V DC, measure the voltage.
