Oscilloscope (V-212 Hitachi)


An oscilloscope is a type of electronic test instrument.
It comprises a screen which typically displays a 2 dimensional graph of constantly varying signal voltages (y axis) with time (x axis).
Oscilloscopes can be used to display any other type of signal which can be converted to a voltage signal.
They are also known as a CROs, standing for Cathode Ray Tube, as originally all oscilloscopes used cathode ray tubes for their display element.

Oscilloscopes include instruments which are used to display the waveform of a heartbeat on an continuous ECG monitor, and also for displays testing automotive ignition system function.
