Test Condition for Picture Quality (Sharpness) Block
Common Test Condition for Picture Quality (Sharpness) Block
1.
SW67 = SW66 = B, SW63 = B, SW60 to SW61 = B, SW44 = ON, SW40 = B, SW18 to SW26 = A, SW77 = OPEN
2.
Send bus control data as preset values, turn ACB operation switching to ACB OFF (00), select Sync input (1), turn P-MODE to Normal 1(000), WPL-LEVEL to
max (111), and change subaddress (1C) to (03).
3.
Input sync signal, which is in sync with input signal for testing except “Sweep”, to #53 (Sync input). “H-Freq.” should be the same frequency as the one of #53.
4.
Set Y/color difference input mode to (0), sync separator level to 20 % (01), and vertical free-running frequency to 307H (110).

OPEN
1. Connect external power supply PS to #68, and monitor #70 and #74.
2.
Set black stretch point 1 to OFF (000), and black detection level to 0 IRE (1).
3.
Increase PS voltage from 4.95 V in steps of 1 mV. At the moment when #70 picture period (High) drops to
Low level, monitor DC difference on #74 VB.
4.
Set black detection level to 3 IRE (0).
5.
Repeat the step 3 above and monitor DC difference, VB3 on #74.
P02

OPEN
1.
Set SW70 to A (maximum gain), and input 500-kHz sine wave to TPA.
2.
Adjust signal amplitude to 0.1 Vp-p on #68.
3.
Set black stretch point 1 to OFF (000), and measure #74 amplitude VA.
4.
Set black stretch point 1 to 001 (black stretch ON), and measure #74 amplitude VB.
5.
Calculate GBS using a following equation.
GBS
= 20 × og
