Counts the horizontal frequency of an input selected by SYNC SW.
To calculate the horizontal frequency (Y) ;
Convert data read from H FREQ DET into decimal value and call it X.
H Freq detection
The error range of X is −1 to +1.
When for SYNC-IN;
When for HD/VD-IN;
Horizontal frequency (Y) = 1 ÷ (0.003 ÷ X) [Hz]
