| 摘 要： | 基于直接数字频率合成芯片AD9959、锁相环芯片ADF4351,结合开源电子平台Arduino（基于微处理器ATmega328）,建立参考到同一个外部频率参考的多路信号源,能够输出频率为0 Hz～4.4 GHz的正弦波,频率、相位、幅度可以通过USB端口和控制面板灵活控制,通过混频和叠加等手段,产生边带调制PDH激光稳频需要的调制信号和解调信号。该信号源集成度高、成本低且能在实验室条件下替代商品仪器应用于边带调制PDH激光稳频等实验,解决了限制边带调制PDH激光稳频推广应用的一个重要障碍。 |

| Abstract: | A 6-channel signal generator with all the output channels share the same external frequency reference is designed based on direct digital synthesizer(DDS) chip AD9959 and phase-locked loop(PLL) chip ADF4351, combined with Arduino (an open-source electronic platform based on microprocessor ATmega328) as the controller. The output range of the signal generator is 0 Hz～4.4 GHz. Its frequency, phase and amplitude are adjustable via the USB port and the control panel. By means of mixing and combining, the modulation and the demodulation RF signal are generated. The signal generator is highly integrated and low-cost, and can be an alternative to commercial signal generators in sideband modulation PDH laser frequency stabilization experiment under laboratory conditions. |
