"instrument for visually recording an electrical wave," 1915, a hybrid formed from Latin oscillare "to swing" (see oscillation) + -scope.

A test device that can capture and display an oscillating electrical signal.

noun. an electronic gadget which documents and expresses visually an electrical or sound current on a fluorescent screen of a cathode ray tube.

A device to measure electrical voltage over a period of time.

Test instrument for visually showing the changes in a varying current by displaying the corresponding voltage wave form on a fluorescent screen.

An electronic device with a screen, which displays a picture of the voltage of an electrical signal. When this device is connected to the output of an audio amplifier, it displays patterns related to [..]

An electronic device that displays, on a video screen, a representation of an electrical signal.

A cathode-ray tube with associated electronic circuits that enable external voltages to deflect the electron beam of the cathode-ray tube simultaneously along both horizontal and vertical axes.

The oscilloscope provides a visual way of investigating electrical signals. The vertical scale shows the voltage of the signal - its scale can be modified by changing the Y-gain setting (in V/div). Th [..]

TC, UE, EL The oscilloscope provides a visual way of investigating electrical signals. In standard grade, you need to understand about the voltage gain and timebase controls of the oscilloscope. The [..]

Electronic testing device that can display wave forms and other information on a TV-screen like cathode ray tube.  As basic fixture in sci-fi movies. 

(n) electronic equipment that provides visual images of varying electrical quantities

The oscilloscope is an electronic instrument widely used in making electrical measurements. The main component of the oscilloscope is the cathode ray tube (CRT). The CRT is a vacuum tube in which electrons are accelerated and deflected under the influence of electric field. The electrons are deflected in various directions by two sets of plate plac [..]

an instrument which produces, on a screen, graphs of potential difference (PD) against time or of one potential difference against another potential difference. A dual-trace oscilloscope can simultaneously produce two PD - time graphs with the same time scale.

A device that displays the wave form created by an electrical generating device such as a generator, inverter, or utility.

An instrument that uses a cathode-ray tube to display waveform images of periodic changes in voltage or current.

     An instrument that displays a plot of voltage over time.  Often referred to as a scope.

An instrument that uses a cathode-ray tube to display waveform images of periodic changes in voltage or current.

A device that produces a visual trace of a voltage or current wave shape, generally on a cathode ray tube.

[top]

A system in which a supplied signal causes the deflection of the electron beam in a cathode-ray tube, thus forming a visible trace on the phosphor screen of the tube, allowing for examination of signa [..]

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 repres [..]

An electronic measurement tool which allows one to view a waveform. The vertical axis shows amplitude and the horizontal axis shows time

An electronic measurement tool which allows one to view a waveform. The vertical axis shows amplitude and the horizontal axis shows time.

A test device which displays voltage curves graphically.

An instrument for making visible the instantaneous values of one or more rapidly varying electrical quantities as a function of time or of another electrical or mechanical quantity.

An electronic measuring instrument that creates a visible two-dimensional graph, on a screen, of one or more continuously varying voltages or currents.
