应用于边带调制PDH激光稳频的信号源设计
Design of Signal Generator Applied on Sideband Modulation Pound-Drever-Hall Laser Frequency Stabilization
摘要
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.关键词
