Function generators are commonly used by engineers, technicians, and scientists to thoroughly and reliably analyze an electronic system. A Cheap Function Generator — also known as an arbitrary waveform generator — produces an oscillating signal with consistent, easy-to-control frequency and amplitude characteristics, making it ideal for testing various kinds of broadcasting equipment.

A common piece of electronic test equipment, a function generator has several high-quality waveforms with accurate, stable frequency and is a convenient source of time-varying electrical signals with an established amplitude, frequency, and waveform.
