問題:

What is the difference between Position and Offset on an oscilloscope?

答案:

To answer this first you need to understand the layout of how your waveform trace is displayed.

On your oscilloscope you generally will see either 8 or 10 divisions vertically on the screen.

Along the left side of the screen you will see a marker which indicates your channels 0V level.

You can move the position of the channels 0 Voltage indicator vertically anywhere on the display.

If the signal you are probing has a voltage offset; you can compensate for the offset by applying a voltage in the scopes offset menu.
