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. | ||

A '''dual-trace''' o'scope has 2 probes, so 2 different signals can be seen -- so not only the shape of the signal can be seen, but also the exact time from events on one signal to events on the other signal. | A '''dual-trace''' o'scope has 2 probes, so 2 different signals can be seen -- so not only the shape of the signal can be seen, but also the exact time from events on one signal to events on the other signal. | ||
