Supplemental Description
(Note 1) REC mode BELL centre frequency (1) (FBLR1) / (2) (FBLR2) :
Input a sine wave (200mVp-p, 4 to 5MHz) to S16 and measure the amplitude at pin 22 using an FET probe.
Assign to FBLR1 / FBLR2 the frequency at S16 when the amplitude is maximized.
(Note 2) REC mode killer operating level (GKLR) :
Input a color bar signal (Fig. 1) to S16 and take 0dB as the color signal level.
Gradually decrease the color signal level at S16 and assign to GKLR [dB] the level at S16 when the voltage at
T28 becomes 2.5V or less, provided that the sync signal at pin 29 lags that at S16 by 1.1μs.
(Note 3) REC EQ centre frequency (1) (FEQR2) / (2) (FEQR2) :
Observe the waveform at T12 when S22 = sine wave (200mVp-p, 4 to 5MHz) is input and assign to FBLR1 /
FBLR2 the frequency at T12 when the amplitude is minimized.
(Note 4) Assign to V15R the voltage at the time of VAGC measurement.
(Note 5) PB EQ centre frequency (1) (FEQP1) / (2) (FEQP2) :
Input a sine wave (50mVp-p, 1 to 1.2MHz) to S14 and assign to FEQP1 / FEQP2 the frequency at S14 when
the signal level is maximized.
(Note 6) PB BELL centre frequency (1) (FBLP1) / (2) (FBLP2) :
Input a sine wave (200mVp-p, 1 to 1.2MHz) to S9 and assign to FBQP1 / FBQP2 the frequency at T18 when
the signal level at T9 is minimized.
