Oscilloscopes An oscilloscope is a system in which a supplied signal causes the deflection of the electron beam in a cathode-ray tube, thus forming a visible trace on the phosphor screen of the tube and providing for examination of signal characteristics. A CRT oscilloscope is particularly convenient for studying repetitive phenomena, but a tube with a long-delay phosphor can be used to analyze a single electrical pulse. An oscilloscope equipped with a camera becomes an oscillograph.

electron beam (e-beam) A stream of electrons emitted by a single source that move in the same direction and at the same speed.
deflection Any bending of a wave of radiation away from its expected path, as, for example, by diffraction or by a magnetic field.
cathode-ray tube (CRT) A vacuum tube with an electron gun at one end and a fluorescent screen at the other. Electrons emitted from a heated filament are accelerated by a series of annular anodes at progressively higher positive voltages. The electron beam is then...
