Definition - What does Oscilloscope mean? An oscilloscope is a piece of equipment used to measure electronic signals, and is found in many scientific laboratories. It is used to observe varying-signal voltages on a two-dimensional grid representing time. When connected to a power source through a probe, the oscilloscope displays the corresponding real-time waveform immediately.
