Abstract

The invention discloses a signal generator 2 with noise signal output function. The signal generator 2 comprises a control unit 21, an input unit 24, a nonvolatile memory 22, a wave shape processing unit 25, and a digital to analog conversion unit 26, wherein the input unit 24, the nonvolatile memory 22 and the wave shape processing unit 25 are connected to the control unit 21; the digital to analog conversion unit 26 is connected with the wave shape processing unit 25; a characteristic parameter 221 is stored in the nonvolatile memory 22 and comprises a starting up frequency 222; the control unit 21 is used for generating an original value related to the starting up frequency 222; the wave shape processing unit 25 is used for utilizing the original value to generate a pseudorandom numbers sequence; and the digital to analog conversion unit 26 is used for performing digital to analog conversion to the pseudorandom numbers sequence. The signal generator 2 provided by the invention solves the problem that the same noise is generated when a user uses the signal generator repeatedly.

Description

technical field [0001] The invention relates to a multi-channel signal generator with the function of outputting noise signals, in particular to a multi-channel signal generator whose output noise has high randomness. Background technique [0002] As a common excitation source, signal generators have been widely used in scientific research and industrial engineering. A typical application of the signal generator is to simulate various signals in the laboratory, as the input stimulus of the circuit and system under test, and provide a simulation environment for testing various performance indicators of the circuit and system under test. Signal generators in the traditional sense are divided into four categories according to their signal waveforms: (1) sinusoidal signal generators: mainly used to measure frequency characteristics, nonlinear distortion, gain and sensitivity of circuits and systems; (2) function ( Waveform) signal generator: generate some specific periodic time...
