Oscilloscope



[uh-sil-uh-skohp] /əˈsɪl əˌskoʊp/

noun, Electricity.
1.
a device that uses a cathode-ray tube or similar instrument to depict on a screen periodic changes in an electric quantity, as voltage or current.
/ɒˈsɪləˌskəʊp/
noun
1.
an instrument for producing a representation of a quantity that rapidly changes with time on the screen of a cathode-ray tube. The changes are converted into electric signals, which are applied to plates in the cathode-ray tube. Changes in the magnitude of the potential across the plates deflect the electron beam and thus produce a trace on the screen
n.

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

oscilloscope os·cil·lo·scope (ə-sĭl’ə-skōp’)
n.
An electronic instrument that produces an instantaneous trace on the screen that corresponds to oscillations of voltage and current.
os·cil’lo·scop’ic (-skŏp’ĭk) adj.
oscilloscope
(ə-sĭl’ə-skōp’)
An electronic instrument used to observe and measure changing electrical signals. The amplitude of the signal as it varies with time is displayed graphically on a screen as a line stretching from left to right, with displacements up and down indicating the amplitude of the signal. Oscilloscopes are used to diagnose problems in electronic signal-processing devises, such as computers or stereos, and to monitor electrical activity in the body, such as that of heartbeats.
