摘　　要：为了实现无线控制信号源的输出,而不依靠于有线连接,设计了一种基于手机终端,ESP32和DDS芯片的无线控制信号源方案。ESP32通过低功耗蓝牙接收手机终端发送的信号控制字,然后对DDS芯片寄存器进行频率控制字写入,实现不同频率的正弦信号输出。测试证明,该设计可以通过手机终端控制实现0~2MHz频带内的稳定正弦信号输出。In order to realize the wireless control output of the signal source,instead of relying on the wired connection,this paper designs a kind of wireless control signal source scheme based on mobile phone terminal,ESP32 and DDS chip.ESP32 receives the signal control word sent by the mobile phone terminal through Bluetooth low energy,and then writes the frequency control word into the DDS chip register to realize the output of sinusoidal signals of different frequencies.Test proves that this design can achieve stable sinusoidal signal output in the 0~2MHz frequency band through the control of the mobile phone terminal.
