[0002] A signal generator is an electronic instrument used to provide various waveform signals required for measurement. It is a commonly used signal source and can be widely used in related fields such as automatic control, scientific experiments, and electronic circuits. When analyzing circuits, it is often necessary to understand The relationship between the output signal and the input signal requires a signal generator to generate a signal to stimulate the system, and at the same time observe and analyze the response of the system to the excitation signal; the current signal generator is more and more widely used, and it also affects the frequency of the signal generator The stability, frequency range and frequency resolution of the output signal put forward higher and higher requirements, especially in the generation control of the noise wave signal, the current signal generator can not meet the demand
