(1) The same procedure as the steps 1 and 2 of the
Note S5.
(2) In the condition that SUB (IF) D6 = 1, measure
amplitudes of color difference signals of pin 35
and pin 36 as VRSA and VBSA respectively, and
find SATTR and SATTB from measurement
results.
SATTR = 20 og (VRSA / VRS),
SATTB = 20 og (VBSA / VBS)

(1) The same procedure as the steps 1 and 2 of the
Note S5.
(2) Input non-modulated 200 Vp-p (R-Y) chroma
signal to pin 42.
(3) Measure noise amplitude nR and nB (mVp-p)
appearing in color difference signals of pin 35 and
pin 36 respectively.
(4) Find S / N ratio by the following equation.
