(1) Input 200 mVp-p (R-Y ID), 75% chroma color
bar signal (SECAM system) to pin 42.
(2) Measure amplitude of R-Y ID output of pin 36
as ebmo.

(1) While supplying 20 mVp-p CW sweep signal
from network analyzer to pin 42 and monitoring
output signal of pin 36 with the network
analyzer, measure frequency having maximum
gain as foBEL of the bell frequency
characteristic.
(2) Find difference between foBEL and 4.286 MHz
as foB-C.

each measurement result from 4.286 MHz as
foB-L or foB-H.

(1) Input 200 mVp-p (R-Y ID), 75% chroma color
bar signal (SECAM system) to pin 42.
(2) Measure color difference levels VRS and VBS
with signals of pin 35 and pin 36.
(3) Calculate relative amplitude from VRS / VBS.
