7. Press “Mode” option button to select “Edge”, “Pulse”, “Slope” or “Video”.

8. Set the trigger according to trigger edge.

9. Press the “Source” option button to select “CH2”.

10. Turn the “S/div” knob to optimize waveform display.

11. Repeat steps 7 and 8.

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” or “Pulse” trigger. Then select the “coupling” option.

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.)

2.8.5 Slope & Level

The Slope and Level controls help to define the trigger. The Slope option (Edge

trigger type only) determines whether the oscilloscope finds the trigger point on the

rising or the falling edge of a signal.

The TRIGGER LEVEL knob controls where on the edge the trigger point occurs.
