ALSO CALLED: Cathode Ray Oscilloscopes
DEFINITION: An oscilloscope is a laboratory instrument commonly used to displayand analyze the waveform of electronicsignals. In effect, the device draws a graph of the instantaneous signal voltage as a function of time. A typical oscilloscope can display alternating current (AC)

OSCILLOSCOPES DEFINITION (continued):
orpulsating direct current ( DC) waveforms having a frequency as low asapproximately 1 hertz ( Hz) or as high as several megahertz ( MHz). High-end oscilloscopes candisplay signals having frequencies up to several hundred gigahertz ( GHz). The display is broken up intoso-called horizontal divisions (hor div) and vertical divisions (vert div). Time isdisplayed from left to right on the horizontal scale. Instantaneous voltage appearson the vertical
