A signal generator is a device that can provide electrical signals of various frequencies, waveforms, and output levels. It is used as the test signal source or excitation source when measuring the amplitude characteristics, frequency characteristics, transmission characteristics and other electrical parameters of various telecommunication systems or telecommunication equipment, as well as the characteristics and parameters of components.
Signal generator, also known as signal source or oscillator, has a wide range of applications in the field of production practice and technology. Various waveform curves are expressed by trigonometric function equations. Circuits that can generate a variety of waveforms, such as triangular waves, sawtooth waves, rectangular waves (including square waves), and sine waves are called function signal generators.
