任意波形信号发生器控制软件设计

Design of Control Software of Arbitrary Waveform Signal Generator

针对传统任意波形发生器成本高,输出波形单一,平滑度不高以及波形恢复和重建能力较差等问题,文中设计了一款控制任意波形发生器输出的软件。该信号源软件通过开发波形叠加算法实现50次谐波的叠加,支持8通道用户自定义波形信号的同步输出与显示,同时通过三角插值算法增加COMTRADE文件的波形数据点,重建波形信号,支持以太网、串口多种通讯方式,并且有谐波试验、波形回放、设备参数设置等功能。测试结果表明:该软件能够模拟多种用户自定义信号,波形展示平滑度高,波形重建效果良好,对波形发生器控制软件的开发设计具有参考价值。

In view of the problems of high cost,single output waveform,low smoothness and poor waveform recovery and reconstruction ability,this paper designed a software to control the output of any waveform generator.The signal source software through the development of waveform superposition algorithm 50 harmonic superposition,supported eight channel user custom waveform signal synchronous output and display,at the same time through the triangle interpolation algorithm,COMTRADE waveform data points were increased,the waveform signals were reconstructed,supporting ethernet,serial communication mode,and harmonic test,waveform playback,equipment parameter setting and other functions.The test results show that the software can simulate a variety of user custom signals,waveform display smoothness,waveform reconstruction effect is good,and has reference value for the development and design of waveform generator control software.
