(1) Supply 4.5V DC to pin 5.
(2) Input video signal to pin 51.
(3) Set the width of pin 6 input pulse to 8s.
(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 5V DC to pin 5, measure HP.
(10) While impressing 4V DC to pin 5, measure HP.
(11) Find difference between the two measurement results obtained in the preceding steps 9 and 10 (HCC).
