What is a Digital Oscilloscope?
An oscilloscope is an electronic instrument that depicts patterns on a screen that are graphical illustrations of electrical signals, and measures and analyzes these signals. Oscilloscopes are particularly useful in observing the exact wave shape of an electrical signal. A digital oscilloscope is an oscilloscope that digitally provides its reading. A grid, called a graticule, is superimposed over the electrical signal that is displayed on an oscilloscope screen. The front panel of an oscilloscope generally has control knobs, display controls, and input connectors. Oscilloscopes can be of the laboratory bench-type variety or the more portable types that can be transported for field work. Some portable types are battery operated.
