A function generator is usually a piece of electronic test equipment used to generate different types of electrical waveforms over a wide range of frequencies. Some of the most common waveforms produced by the function generator are the sine, square, triangular and sawtooth shapes. These waveforms can be either repetitive or single-shot (which requires an internal or external trigger source). Integrated circuits used to generate waveforms may also be described as function generator ICs.

Although function generators cover both audio and RF frequencies, they are usually not suitable for applications that need low distortion or stable frequency signals. When those traits are required, other signal generators would be more appropriate.

Some function generators can be phase-locked to an external signal source (which may be a frequency reference) or another function generator.

Function generators are used in the development, test and repair of electronic equipment. For example, they may be used as a signal source to test amplifiers or to introduce an error signal into a control loop.

Function Generator is a device that is used to generate wide range of AC signals. A function generator is also known as “signal generator” or “waveform generator”. A function generator generates a variety of periodic and single shot waveforms of different periods and amplitudes. The function selector buttons allow you to select the type of waveform you want. The property selector buttons allow you to edit the various properties of the wave like amplitude, frequency etc. you can start editing by clicking on the display and typing from the keyboard directly also.
