摘要
针对目前用于航空测试仪器校准的信号源现状,提出了一种基于PC104总线和直接数字频率合成技术的程控信号源设计方案。介绍了整个信号源系统的构成与工作原理,并详细叙述了其中DDS信号发生模块和功率放大模块的硬件设计。
According to the present conditions of signal generator for the aviation testing instrument calibration, a design plan for signal generator based on PC104 bus and direct digital synthesize（DDS） is put forward. The structure and function principle of whole signal generator is introduced, and the hardware design of DDS signal generation module and power amplified module are discussed in detail.
