MEASUREMENT METHOD
Set the bus control data to the preset value.
Set SW₅₄ to A and input a sweep signal to TP54.
Set the amplitude of #54 to 20 mV_p-p.
Set the unicolor to the maximum (111111), set the brightness to the center (1000000), set the RGB cutoff to the
center (10000000), turn the Y mute off (0), turn test mode on (0), and set the picture sharpness to the maximum
(111111).
Connect an emitter-follower to TP13 (R OUT) and use a spectrum analyzer to observe TP13 (R OUT).
Seek the peak point frequency F_AP as shown in the diagram.
P₁₆ Sharpness Peak Frequency A
B OPEN
Note 1: When testing, see the picture sharpness test circuit diagram. First turn ACB mode off (bus control).
Note 2: Ensure the composite signal is always input to pin 38 (SYNC IN).
