摘　　要：针对多路信号拼接技术中多路信号在相位、频率及幅值上均需达到精确可控的要求,在完成可控时钟信号模块设计的基础上,结合AD9910具有多芯片协同工作的功能,提出了一种能够实现最高频率可达400 MHz的多通道可控的中频信号源设计方案。测试结果表明多通道可控中频信号源达到了多路同步的苛刻要求,这为多路窄带信号拼接为单路宽带信号打下了坚实基础,提供了技术上与硬件上的支持。Accurate control parameters of phase,frequency and scope are needed in multi-signal synthesis,so a controllable multi-channel signal generator is designed and the highest frequency is up to 400 MHz based on the coordinate function of AD9910 and the controllable clock signal of clock group. Measured results show that the generator possesses the capacity of generating controllable multi-signal,after the adjustment by using the oscillograph. This design establishes a foundation of multi-channel signal synthesizing.
