Abstract

The embodiments of the present invention disclose a terminal fitting-based arbitrary signal generator and an output control method thereof. With the terminal fitting-based arbitrary signal generator and the output control method thereof adopted, uninterrupted output of fitted signals can be realized, and high-precision dynamic waveforms can be outputted for a long time. According to the embodiments of the present invention, the terminal fitting-based arbitrary signal generator includes a digital signal processor and a digital-to-analog converter; the digital signal processor is connected witha terminal; the digital signal processor includes a random access memory and a DMA controller; the random access memory is provided with two buffer zones; and the DMA controller is connected with thebuffer zones and the digital-to-analog converter.

Description

technical field [0001] The invention relates to the field of signal generators, in particular to an arbitrary signal generator based on terminal fitting and an output control method thereof. Background technique [0002] The development of the power system is accompanied by the consideration of the deterioration of power quality, especially the increasing number of low-quality power generation systems such as wind, photovoltaic, and distributed power generation systems, as well as the disturbance to the power grid such as high-speed rail, electric vehicles, and energy storage. More and more attention has been paid to the study of distorted signals subjected to severe perturbations. Usually, voltage sources and current sources (signal generators are signal sources) are used to test various instruments and meters, or to study the characteristics of power grid systems. However, traditional sources usually only output DC or AC and superimposed harmonics, which is obviously not ...
