(1) Supply 4.5 V DC to pin 5.
(2) Input video signal to pin 48.
(3) Set the width of pin 6 input pulse to 8 s.
(4) Measure φFBP shown in the figure below (φFBP).
(5) Adjust the phase of pin 6 input pulse so that the center of pin 4’s output pulse corresponds to the trailing
edge of input sync. signal.
(6) Set bus data as indicated on the left and measure the horizontal picture position with respective bus data
settings (HSFTmax, HSFTmin).
(7) Find HP difference between the conditions mentioned in the above step 6 (HSFT).
(8) Reset bus data to the preset value.
(9) While impressing 5 V DC to pin 5, measure HP.
(10) While impressing 4 V DC to pin 5, measure HP.
(11) Find difference between the two measurement results obtained in the preceding steps 9 and 10 (HCC).
Unless otherwise specified : H, RGB VCC=9V ; VDD, Fsc VDD, Y / C VCC=5V ; Ta=25±3°C ; BUS=preset value ;
pin 48 input video signal=50 system
