Test Method
Input signal 1(f₀ = 100 kHz, picture period amplitude = 0.2 Vp-p) from pin 68. Control drive
gain adjustment data so that pins 14 and 13 picture period amplitude equals that of pin 12.
Set brightness data to 108.
Measure pins 4, 6, and 7 voltage. Apply measured voltages from external power supply.
3. Set subaddress (02) data to (40).
4. Use output signals from pins 12, 13, and 14, and measure ACB insertion pulse phase as
shown in the Figure 1.
Note: Take picture period following FBP input fall after V・BLK ends as phase 1H. After next H･
BLK, count the phase as 2H, 3H, and so on.

5. Monitor pins 12, 13, and 14. Measure ACB insertion pulse amplitudes (level from picture
period amplitude at quiescent.): VACB1R, VACB1G, and VACB2B.
6. Set subaddress (02) data to (80), and repeat the step 5 above: VACB2R, VACB2G, and
VACB2B.
7. Set subaddress (02) data to (C0), and repeat the step 5 above: VACB3R, VACB3G, and
VACB3B.
