Supplemental Description
(Note 1) REC mode BELL center frequency (FBLR1, FBLR2, FBLR3) :
Input a sine wave (200mVpp, 4 to 5MHz) to T16 and measure the amplitude at T20. Assign to FBLR1 (T10=OPEN),
FBLR2 (T10=0V), FBLR3 (T10=5V) the frequency at T16 where the amplitude is maximized.

(Note 3) REC EQ (1.1MHz A-BELL) center frequency (FEQR) :
Observe the waveform at T11 when T12=sine wave (200mVpp, 4 to 5MHz, BIAS=4V) is input and assign to FEQR
the frequency at T11 where the amplitude is minimized.
(Note 4) Assign to V15R the voltage of T15 at the time of VAGC measurement.
(Note 5) PB EQ (1.1MHz BELL) center frequency (FEQP) :
Input a sine wave (50mVpp, 1 to 1.2MHz) to T14 and assign to FEQP the frequency at T14 where the signal level of
T11 is maximized.
(Note 6) PB 4.3MHz A-BELL center frequency (1 FBLP1) / (2 FBLP2) / (3 FBLP3) :
Input a sine wave (200mVpp, 1 to 1.2MHz, BIAS=4V)) to T18 and assign to FBQP1 (T10=OPEN), FBQP2
(T10=0V), FBEQP3 (T10=5V) the frequency at T18 where the signal level at T20 is minimized.

(Note 7) REC mode sync gate start time, release time (TRGB, TRGE) :
Input Copm. Sync to T29 and assume the sync gate start time (TRGB) as the time from which the signal at T12
attenuates until the signal at T29 rises and assume the sync gate release time (TRGE) as the time from which the
horizontal sync signal rises till the signal at T12 increases (Fig. 2).
