*2 Measuring horizontal sync signal pull-in range for NTSC
With TP1 waveform not synchronized to signal 1, adjust signal 1 frequency toward 15.734kHz. The
measurement value is the smaller of the synchronized frequency and the difference from 15.734.
*3 Measuring horizontal sync signal pull-in range for PAL
With TP1 waveform not synchronized to signal 1, adjust signal 1 frequency toward 15.625kHz. The
measurement value is the smaller of the synchronized frequency and the difference from 15.625.
*4 Measuring sync separation level
Gradually lower staircase wave signal sync tip level, and measure sync tip level when Pin 9 waveform
starts to change.
