A graph-displaying device-it draws a graph of an electrical signal.
The oscilloscope is basically a graph-displaying device-it draws a graph of an electrical signal. In most applications the graph shows how signals change over time: the vertical (Y) axis represents voltage and the horizontal (X) axis represents time. The Oscilloscope. The oscilloscope is basically a graph-displaying device-it draws a graph of an electrical signal. In most applications the graph shows how signals change over time: the vertical (Y) axis represents voltage and the horizontal (X) axis represents time. An oscilloscope is a laboratory instrument commonly used to display and analyze the waveform of electronic signals. Oscilloscopes are used to observe the change of an electrical signal over time, such that voltage and time describe a shape which is continuously graphed against a calibrated scale. The observed waveform can be analyzed for such properties as amplitude, frequency, rise time, time interval, distortion and others. Definition of OSCILLOSCOPE. : an instrument in which the variations in a fluctuating electrical quantity appear temporarily as a visible wave form on the fluorescent screen of a cathode-ray tube. — os·cil·lo·scop·ic \ae-ä-ˌsi-lə-ˈskae, ˈskä-pik-ˌae-\ ˌä. sə lə adjective The oscilloscope can be adjusted so that repetitive signals can be observed as a continuous shape on the screen. A storage oscilloscope allows single events to be captured by the instrument and displayed for a relatively long time, allowing observation of events too fast to be directly perceptible. The illustration shows two common waveforms as they might appear when displayed on an oscilloscope screen. The signal on the top is a sine wave; the signal on the bottom is a ramp wave. It is apparent from this display that both signals have the same, or nearly the same, frequency. Intro. An oscilloscope's primary function is to provide a graph of a signal's voltage over time. This is useful for measuring such things as clock frequencies, duty cycles of pulse-width-modulated signals, propagation delay, or signal rise and fall times.
