We design and complete a multi-frequency source current module, applying the Direct Digital Synthesis (DDS) technology. We use the DSP chip as our controller and the frequency, phase and amplitude of the signal are all programmable and adjustable.

• 设计并完成了多频恒流源模块,采用了直接数字合成(Direct Digital Synthesis,DDS)技术,应用数字信号处理器(DSP)作为控制器,实现了频率、相位和幅值均动态可调。
