(1) Activate the test mode (S26-ON, Sub Add 02 ; 08h).
(2) Connect band pass filter (Q = 2), set to TV mode (fo = 600 kHz) with 0dB attenuation.
(3) Set the crystal mode to conform to European, Asian system and set the gate to normal
status.
(4) Input 3N, 4N and 4P rainbow color bar signals having 100 mVp-p burst to pin 42 of the
chroma input terminal one after another.
(5) Measure amplitudes of color difference signals of pin 36 (B-Y) and pin 35 (R-Y)
respectively, and express them as 3NeB-Y / R-Y, 4NeB-Y / R-Y and 4PeB-Y / R-Y
respectively.
(6) While inputting 4P 75% color bar signal (100 mVp-p burst) to pin 42 of the chroma input
terminal, measure amplitudes of color difference signals of pin 36 (B-Y OUT) and pin 35
(R-Y OUT) respectively. (Ratio of those amplitudes is expressed as 4Peb-y / r-y for
checking color level of SECAM system.)

(4) Input 3N, 4N and 4P rainbow color bar signals having 100 mVp-p burst to pin 42 of the
chroma input terminal one after another.
(5) Measure amplitudes of color difference signals of pin 36 (B-Y) and pin 35 (R-Y)
respectively, and express ratio between the two amplitudes as 3NG R / B, 4NG R / B
and 4PG R / B respectively.
(Note)
Relative amplitude of G-Y color difference signal shall be checked later in the
