Part of the Electronics glossary: An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time.
An oscilloscope is only good if you can actually connect it to a signal, and for that you need probes. Probes are single-input devices that route a signal from your circuit to the scope. They have a sharp tip which probes into a point on your circuit.n oscilloscope is only good if you can actually connect it to a signal, and for that you need probes.
