3. Vertical Scan Line Adjustment
4. Adjustment at the scan end side.
If the waveform has two dropouts at the scan end side, move down the right side of the SBU to make the dis-
tance between peaks narrower. The distance between peaks has to be within 50
µ
s.
If the waveform has three dropouts at the scan end side, move up the right side of the SBU to make the dis-
tance between peaks narrower. The distance between peaks has to be within 50
µ
s.
5. After adjusting the scan end side, confirm that the scan start side is still adjusted properly, as the adjustment at
one side often changes the waveform at the other side.
