脉冲发生器（Pulse generator） The classification of pulse generator According to the signal waveform is divided into four categories: The sine signal generator. Mainly used for measuring circuit and frequency characteristics of the system, nonlinear distortion, gain and sensitivity etc.. According to their different properties and applications can also be divided into low frequency (20 Hz to 10 MHz) signal generator, high-frequency (100 kHz to 300 MHz) microwave signal generator, signal generator, frequency sweep and program-controlled signal generator, frequency synthesis signal generator. The function (wave) signal generator. Can produce certain periodic function of time waveform (sine wave, triangle wave, sawtooth wave, Fang Bo and pulse wave) signal, frequency range from a few micro Hz to tens of mhz. In addition to communication, instrumentation and automatic control system testing, also widely used in other non electric measurement. The pulse signal generator. Can produce width, amplitude and repetition frequency rectangular pulse generator, can be used to test the response of linear system transient, or as an analog signal to test radar, pulse and other digital multiplex communication system performance. The random signal generator. Usually divided into noise signal generator and the pseudorandom signal generator two. Noise signal generator is mainly used for: in a random signal into the test system, to simulate the actual working conditions of noise in the measurement system performance; and a known noise signal and noise within the system by determination of noise coefficient; random signal instead of sine or pulse signal to determine the dynamic characteristics of the system. When the correlation function measurement using the noise signal, if the average measurement time is not long enough, there will be a statistical error, can be used to solve the pseudo random signal.
