摘　　要：信号源采用小型模块化设计,由多个体积小巧的信号产生模块实现功能。模块使用FPGA控制DAC和PLL实现功能,同时为了进一步缩小体积,模块上的DAC与PLL间采用直连设计。单个模块可独立编程设置,选择输出中频信号或者时钟信号,每台信号源中的模块数量也可根据实际需求灵活选择。该信号源经过验证满足要求,可以为高速电路调试提供良好保障。The signal source introduced in the article adopts a small modular design,and functions are realized by multiple small signal generating modules.The module uses FPGA to control the DAC and PLL to achieve functions.At the same time,in order to further reduce the size,the DAC and PLL on the module adopt a direct connection design.A single module can be independently programmed and set to choose to output an IF signal or a clock signal.The number of modules in each signal source can also be flexibly selected according to actual needs.The signal source has been verified to meet the requirements and can provide a good guarantee for high-speed circuit debugging.
