The signal generator is a device which can provide various frequency, waveform and output level electrical signals. It is widely used in the field of production practice and science and technology.
Signal generator in amplitude characteristics, measurement of various telecommunication systems or telecommunications equipment frequency characteristics, transmission characteristics and other electrical parameters, and the characteristics and parameter measurement of components, used as a test signal source or excitation source.
Signal modulation functions: signal modulation refers to the modulated signal, amplitude, phase or frequency change of the carrier signal frequency information is embedded into the high frequency, the signal can be transmitted from voice to data, and to any video signal.
