Coupling

Use “Coupling” to make sure the signal passes through the trigger circuit.

It is useful for obtaining a steady wave form.

If you use trigger coupling, you should press the “TRIGGER” button and

then select “Edge”, “Pulse”, “Video”, or “Slope” trigger. Then select the

“coupling” option in the “Set Up menu”.

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.)

Slope and 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.
