oscilloscope

oscilloscope
An oscillograph in which the record of oscillations is continuously visible.
- cathode ray o. (CRO) the common form of o., in which a varying electrical signal (y) vertically deflects an electron beam impinging on a fluorescent screen, while some other function (x or time) deflects the beam horizontally; the result is a visual graph of y plotted against x or time with negligible distortion by inertia.
- storage o. a cathode ray o. in which the visual record of oscillations persists on the fluorescent screen until erased electrically.

n.
a cathode-ray tube designed to display electronically a wave form corresponding to the electrical data fed into it. Oscilloscopes are used to provide a continuous record of many different measurements, such as the activity of the heart and brain. See electrocardiography, electroencephalography.
