b
(1)
Set sub-address (00) 40 and (02) 82.
(2)
Input signal b (horizontal 31.5 kHz ) to pin 11 (HD3-IN).
(3)
Measure the phase difference HD3PH between pin 11 and pin 6 (AFC filter) wave form.
HA03
Polarity distinction active range
c
b
(1)
Set sub-address (00) 70 and (02) 82.
(2)
Input signal b ((horizontal 31.5 kHz ) to pin 11 (HD3-IN).
(3)
Decreasing the duty of signal b to 0% (get negative period shorter), measure the duty of Signal b
(HD-DUTY1) when the phase between pin 11 and pin 13 (HD1-OUT) change.
(4)
Increasing the duty of Signal b to 100% (get negative period longer), measure the duty of Signal b
(HD-DUTY2) when the phase between pin 11 and pin 13 (HD1OUT) change.
