Test Method
Input signal 1 (f₀ = 100 kHz, picture period amplitude 0.2 Vp-p) from pin 68.
Measure picture period amplitude of pin 13 when subaddress (0D) data is changed to
maximum (FE), center (80), and minimum (00).
3. Use picture period amplitude at center as the base. Determine amplitude ratio DR_G1+ and
DR_G1− at maximum and minimum in decibels.
4. Repeat the steps 1 to 3 above to measure amplitude ratio of pin 14, DR_B1+ and DR_B1− in
decibels when subaddress (0E) data is changed.
5. Repeat the steps 1 to 3 above to measure amplitude ratio of pin 13, DR_G2+ and DR_G2− in
decibels when subaddress (0E) center data is set to (81) used as the base.
6. Repeat the steps 1 to 3 above to measure picture period amplitude ratio of pin 14, DR_B2+
and DR_B2− in decibels when subaddress (0E) data is changed to maximum (FF), center (81),
and minimum (01).
7. Repeat the steps 1 to 3 above to measure picture period amplitude ratio of pin 12, DR_R1+
and DR_R2− in decibels when subaddress (0D) data is changed to maximum (FF), center (81),
and minimum (01).
8. Repeat the steps 1 to 3 above to measure picture period amplitude ratio of pin 14, DR_B3+
and DR_B3− in decibels when subaddress (0D) data is set to (81), and subaddress (0E) data
is changed.
9. Repeat the steps 1 to 3 above to measure picture period amplitude ratio of pin 13, DR_G3+
and DR_G3− in decibels when subaddress (0E) data is set to (81), and subaddress (0D) data
is changed to maximum (FF), center (81), and minimum (01).
10. Repeat the steps 1 to 3 above to measure picture period amplitude ratio of pin 12, DR_R2+
and DR_R2− in decibels when subaddress (0D) data is set to (81), and subaddress (0E) data
is changed to maximum (FF), center (81), and minimum (01).

A 1. Connect external power supply, an ammeter, and a voltmeter to pin 78. Adjust voltage so that
current value is set to zero.
2. Measure the current when voltage of pin 78 is increased by 0.2V. (l_in)
