(1) The same procedure as the step 1 of the Note S5.
(2) Measure output waveforms of pin 35 and pin 36
to find the period between the two points shown in
the figure in time.
(3) In the condition that SUB (IF) D5 = 1, perform the
same measurement as the above step 2.
Measurement results are expressed as trfBW and
trfRW.

(1) Input 200mVp-p (R-Y ID) standard 75% color bar
signal (SECAM system) to pin 42.
(2) Attenuate the input signal to pin 42. Measure R-Y
ID signal level at pin 42 that turns on / off the killer
as eSK and eSC.
(3) In the condition that SUB (IF) D3 = 1, perform the
same measurement as the above step 2 and
express the measurement results as eSFK and
eSFC.
(4) In the condition that SUB (IF) D3 = 0, D2 = 1,
perform the same measurement as the above
step 2 and express the measurement results as
eSWK and eSWC.
