Input signal 1 (f
Change unicolor data to maximum (7F), center (40), and minimum (00) and measure pin 43
picture period amplitude, V
Calculate amplitude ratio of V
Input signal 2 from pin 3 and adjust pin 43 picture period output amplitude to 1 Vp-p.
Change brightness data to maximum (7F), center (80), and minimum (00) and measure pin
43 voltages, V
Set subcontrast to maximum.
Apply external power supply to pin 3 and gradually increase voltage from 5.8 V.
When picture period of pin 43 is clipped, measure pin 43 picture period amplitude voltage,
V
Change subaddress (0C) data to (FC) and repeat the steps 1 to 3 above. (V
Apply external power supply to pin 3 and gradually decrease voltage from 5.8 V.
When picture periods are clipped, measure pins 41, 42, and 43 voltage, V
Adjust brightness data so that picture period voltage of pin 41 is 2.4 V.
Set color data to minimum.
Measure noise levels n41-, n42-, and n43-Vp-p in picture period of pin 41, 42, and 43 with an
oscilloscope.
Calculate S/N.
Input signal 1 (f
Measure pin 41 picture period amplitude v41A.
Apply 1.5 V to pin 52 from external power supply.
Measure pin 41 picture period amplitude v41B
Calculate the following equation. G
Stop applying voltage to pin 52. Set subaddress (1A) to data (E2) and measure pin 41-picture
period amplitude, v41C.
Calculate the following equation. G
