(1)
Activate the test mode (S26-ON, Sub Add 02 ; 08h).
(2)
Connect band pass filter (Q = 2), set to TV mode (fo = 600kHz) 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 100mVp-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 (100mVp-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.

(1)
Activate the test mode (S26-ON, Sub Add 02 ; 08h).
(2)
Connect band pass filter (Q = 2), set to TV mode (fo = 600kHz) 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 100mVp-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 Text section.
