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.
