F0BPFN
F0BPFP
Input SIG6 (VL =0 mV) to (A) and SIG2 (0dB,
frequency variable) to (B). Obtain frequencies
fc1 and fc2 which reduce the output amplitude
by 3dB from the maximum output at TP51 by
changing the frequency, and calculate F0BPF
= (fc1 + fc2)/2. Settings 1 and 3 are required.

(0dB, frequency variable) to (B).
NTSC
Assume TP51 when the center

–23 –15 dB
frequency is input as 0dB and measure
the output level at TP51 when the
frequencies noted on the right are
input. Settings 1 and 3 are required.

ATRAPN
ATRAPP
Input SIG2 (0dB, 3.58MHz, 4.43MHz) to (A) and
measure the output at TP41 with a spectrum
analyzer. Assume the output during Y/C mode
(SW8 = A) as 0dB and measure the amount of
attenuation during COMP mode (SW8 = C).
Settings 1 and 3 are required.

R-Y, B-Y and LPF DEMLP
characteristics
Input SIG6 (VL = 0mV) to (A) and SIG2 (amplitude
100mV, frequency variable) to (F) and (G). Assume the
output amplitude at TP41 when 100kHz is input as 0dB,
and measure the frequency which attenuates the output
amplitude by –3dB.
