摘　　要：基于STM32F429单片机控制系统设计了一款可远距离精确控制频率和幅度值的音频信号发生器。该发生器通过PC控制面板,按照要求输入所需频率、幅度值,借助以太网把控制命令远距离地传输给该发生器,经发生器的处理,把音频模拟信号传输给被测设备。与传统音频信号发生器相比,该发生器可同时输出两路相同的音频信号,不用粗调、细调,直接在PC控制面板上输入所需幅度频率即可,而且能远距离控制。This article designs an audio signal generator based on the control system of STM32F429 microcontroller, which can accurately control the frequency and amplitude remotely. According to the requirements, the generator inputs required amplitude and frequency through the PC control panel,which remotely transmits control command to the generator with the help of Ethernet, then the analog audio signal is transmited to the device under test through the processing of generator. Compared with the traditional audio signal generator, the generator can output two identical audio signal, not coarse, fine, directly inputs desired frequency and amplitude in the PC control panel, and can control remotely.
