扫频信号发生器是一种信号激励装置。
Sweep signal generator is a device that generates excitation signal.
扫频信号发生器有自动扫频、手控、程控和远控等工作方式。
Sweep sweep signal generator with automatic, manual, program-controlled and well-controlled manner, and so on.
基于此理论，本文用CPLD通过编程实现DDS，完成了扫频信号发生器的设计，此系统具有很高的性价比。
Based on the theory, DDS is realized with CPLD through program and the design of sweep signal generator is finished. And the system will have high price performance ratio.
