*2 Measuring horizontal sync signal pull-in range for NTSC
Adjust signal 1 frequency toward 15.734kHz. The measurement value is the smaller of signal 1 frequency
when TP2 level switches from high to low, and the difference from 15.734.
*3 Measuring horizontal sync signal pull-in range for PAL
Adjust signal 1 frequency toward 15.625kHz. The measurement value is the smaller of signal 1 frequency
when TP2 level switches from high to low, 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 TP2 level switches
from low to high.
*5 Sync discrimination switching voltage measurement
Gradually change the voltage impressed on TP1, and measure TP5 voltage when TP2 output switches.
