Input a composite video signal to #38 and measure the V mask period of the #40 (AFC1 FILTER) waveform.
TEST CONDITIONS (DEF V
When the number of H periods in the #33 (VD out) waveform changes from 297 to 225, increase the
voltage from 3 V and measure the value at
When the subaddress (0D) D
When #38 (Sync in) is connected to GND, measure the #39 (VSEP FILTER) voltage.
Set the voltage to around 7.5 V, equivalent to when #40 (AFC1 FILTER) has no load. When a signal as
shown in the diagram below is input to #38 (Sync in) from TG7, calculate V
waveform.
