Introduction
Advanced electronics labs use both oscilloscopes and function generators. A function generator produces signals that provide a specifiable voltage applied over a particular time, such as sine wave or triangular wave signal. Signals generated by the device are used to control other devices to, for instance, vary magnetic field, send radioactive source back and forth, or act as a timing signal. An oscilloscope is used as a signal analyzer: they show the picture of the signal usually in the form of voltage versus time. The experimenter learns about the amplitude, frequency, and the shape of the signal. The tow ...
