oscilloscope, scope, cathode-ray oscilloscope, CRO(noun)
electronic equipment that provides visual images of varying electrical quantities
An electronic measuring instrument which provides a visual representation of the time variation of electrical quantities, such as voltage or current. It may be used to measure the shape of a voltage pulse or the frequency of an oscillating voltage. It can also be used to measure properties of other physical variables, such as sound or light intensity, if they can be translated into electrical voltage or current. The common cathode-ray oscilloscope uses a cathode-ray tube to project a beam of electrons onto the interior of a nearly flat surface surface of the tube, which is coated with a material which fluoresces when struck by the moving electrons. The location of the beam of electrons on the target surface is controlled by electrodes surrounding the point of origin of the beam, which control the horizontal and vertical deflection. The degree of deflection from the vertical center can be made to represent the electrical variable to be measured. The cathode-ray oscilloscope is similar in many respects to the most common form of television tube. -- os*cil"lo*scop`ic, a.
Origin: [L. oscillare to swing + -scope.]
An electronic measuring instrument that creates a visible two-dimensional graph, on a screen, of one or more continuously varying voltages or currents.
An oscilloscope, previously called an oscillograph, and informally known as a scope, CRO, or DSO, is a type of electronic test instrument that allows observation of constantly varying signal voltages, usually as a two-dimensional graph of one or more electrical potential differences using the vertical or y‑axis, plotted as a function of time. Many signals can be converted to voltages and displayed this way. Signals are often periodic and repeat constantly so that multiple samples of a signal which is actually varying with time are displayed as a steady picture. Many oscilloscopes can also capture non-repeating waveforms for a specified time and show a steady display of the captured segment. Oscilloscopes are commonly used to observe the exact wave shape of an electrical signal. Oscilloscopes are usually calibrated so that voltage and time can be read as well as possible by the eye. This allows the measurement of peak-to-peak voltage of a waveform, the frequency of periodic signals, the time between pulses, the time taken for a signal to rise to full amplitude, and relative timing of several related signals.
