4 Measuring sync separation level
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.
Gradually lower staircase wave signal sync tip level, and measure sync tip level when Pin 9 waveform
starts to change.
