7. Press the CH1 button and turn the “S/div” knob to optimize waveform
display.
8. Press “Mode” option button to select “Edge”, “Pulse”, “Slope” or “Video”.

2.8.3 Coupling
Use the “Coupling” to make sure the signal that passes the trigger circuit. It is
useful for us to gather a steady wave form.
If you use the trigger coupling, you should press the “TRIGGER” button and then
select “edge”, “Pulse”, “Video” or “Slope” trigger. Then select the “coupling” option
in “Set up menu”.
2.8.4 Position
The horizontal position control establishes the time between the trigger position
and the screen center. You can adjust the horizontal “POSITION” knob control to
view waveform data before the trigger, after the trigger, or some of each. When
you change the horizontal position of a waveform, you are changing the time
between the trigger and the center of the display actually. (This appears to move
the waveform to the right or left on the display.)
