An oscilloscope is an electronic test instrument that allows visual observation of one or more electrical voltages and their change over time on a display device. The oscilloscope displays a history graph, usually as a two-dimensional graph, where the horizontal x-axis represents time and the vertical y-axis the voltages that are to be displayed. The resulting image is called an oscillogram.
