Abstract

The invention discloses a method and a system for automatically correcting DAC channel communication instability, which are used for solving the problem of waveform signal errors caused by DAC channelcommunication instability in the power-on or reset process and the like. The method comprises the steps of transmitting a correction waveform signal according to pre-stored correction waveform data;obtaining a correction waveform signal after digital-to-analog conversion; judging whether the acquired correction waveform signal is wrong or not according to the pre-stored correction waveform data;and under the condition that the acquired correction waveform signal is wrong, reconfiguring a digital-to-analog converter until the acquired correction waveform signal is correct. Through the method, automatic correcting of the problem of unstable DAC channel communication is realized to obtain a normal waveform signal.

Description

technical field [0001] The present application relates to the technical field of signal generators, in particular to a method and system for automatically correcting DAC channel communication instability. Background technique [0002] In the process of electronic system design, arbitrary waveform generators are indispensable in the process of circuit hardware debugging and circuit testing. [0003] In the process of using the arbitrary waveform generator, it is often necessary to repeatedly power on or reset the arbitrary waveform generator. [0004] In this case, the communication condition of the DAC channel of the digital-to-analog converter may be unstable, thereby affecting the transmitted waveform signal, resulting in an error of the waveform signal. Contents of the invention [0005] The embodiment of the present application provides a method and system for automatically correcting the unstable communication of the DAC channel, so as to solve the problem that the c...
