1)
Input signal 2 to pin 3. Gradually increase the picture period amplitude A.
2)
When pin 13 is clipped, measure the picture period amplitude of pin 13.
3)
As in steps 1) and 2) above, input to pin 4 and measure pin 14, then
input to pin 5 and measure pin 15.

C
1)
Apply an external power supply to pin 3. Gradually decrease the voltage
from 5V DC. When pin 13 is clipped, measure the voltage of pin 13.
2)
As in step 1) above, apply to pin 4 and measure pin 14, then apply to pin
5 and measure pin 15.

C
1)
Input signal 1 (f = 100 kHz, picture period amplitude = 0.2 Vp-p) to pin 3.
2)
When the subaddress (00, unicolor) data are changed to the maximum
(3F), the center (20), and the minimum (00), measure the picture period
amplitude of pin 13.
(vuTXR1, vuTXR2, vuTXR3)
3)
Calculate the maximum and minimum amplitude ratios in decibels.
4)
As in steps 1), 2) and 3) above, input signal 1 to pin 4 and measure pin
14, then input signal 1 to pin 5 and measure pin 15.

C
1)
Input signal 2 to pins 3, 4, and 5.
2)
Adjust the signal 2 amplitude A so that the picture period amplitude of pin
13 is 0.5 Vp-p.
3)
When the subaddress (05, RGB brightness) data are changed to the
maximum (F8), the center (88), and the minimum (08), measure the
picture period amplitudes of pins 13, 14, and 15.
