(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 and 4N rainbow color bar signals having 100mVp-p burst to pin 42 of the
chroma input terminal one after another.
(5)
Measure higher harmonic (2fc = 7.16MHz or 8.87MHz) of 3N and 4N color bar signals
appearing in color difference signals of pin 36 (B-Y OUT) and pin 35 (R-Y OUT)
respectively, and express them as 3N-HCB / R and 4N-HCB / R.

(1)
Activate the test mode (S26-ON, Sub Add 02 ; 08h).
(2)
Connect band pass filter (Q = 2) and set bus data for the TV mode (fo = 600kHz).
(3)
Set the X’tal clock mode to conform to European, Asian system and set the gate to
normal status.
(4)
Input 3N rainbow color bar signal whose burst is 100mVp-p to pin 42 of the chroma
input terminal.
(5)
Measure amplitude of color difference output signal of pin 36 (B-Y OUT) with 0dB
attenuation set by the bus control.
Set the amplitude of the color difference output of pin 36 (B-Y OUT) to 0dB, and
measure amplitude of the same signal with different attenuation of 2dB, 1dB and
+1dB set by the bus control.
