An '''oscilloscope''' (often abbreviated '''o'scope''' or '''scope''') displays signal voltages as a 2-D graph, usually as voltage (vertical axis) as a function of time (horizontal axis). | An '''oscilloscope''' (often abbreviated '''o'scope''' or '''scope''') displays signal voltages as a 2-D graph, usually as voltage (vertical axis) as a function of time (horizontal axis). | ||

The ''probe'' of a o'scope is held against, or is clipped to, the metal wire carrying the signal of interest. | The ''probe'' of a o'scope is held against, or is clipped to, the metal wire carrying the signal of interest. | ||
