According to the signal waveform, the function can be divided into sine signal (waveform) signal, pulse signal and random signal generator and so on four categories. Signal generator also called source or oscillator, in production practice and science and technology has been widely used in the field. Various waveform curve can be represented with trigonometric function equation. Can produce various waveform, such as triangle wave, sawtooth wave, rectangle wave (including square wave), sine wave of the circuit is called a function signal generator. Also known as the signal generator, which is used to produce specific parameters required for the circuit being measured electric testing signal. In testing, research, or adjust the electronic circuits and devices, measurement circuit of some electric parameters, such as measuring the frequency response, noise coefficient, for voltmeter, etc, are required to conform to the conditions set by the technology of electrical signals, to simulate a used in the actual work of excitation signal of the device under test. When the requirement of system steady state characteristics of the measurement, need to use sine signal source of known amplitude and frequency. When the transient characteristics of the testing system, and to use front time, pulse width and repetition period known rectangular pulse source. And the parameters of the signal source output signal, such as frequency, waveform, the output voltage, or power, can under certa
