Description: 以SPCE061A单片机（ Single Chip Micyoco）为核心，通过DDS合成技术设计制作了一个步进值能任意调节的多功能信号源。该信号源在1KHz～10MHz范围能输出稳定可调的正弦波，并具有AM、FM、ASK和PSK等调制功能。信号输出部分采用低损耗电流反馈型宽带运放作电压放大，很好地解决了带宽和带负载能力的要求。系统带中文显示和键盘控制功能，操作简便，实现效果良好。
内含 原程序，正弦信号发生器的pCB原理图，以及一些相关论文。-to SPCE061A (Single Chip Micyoco) at the core, DDS technology through the design of an arbitrary value of Step-conditioned multi-purpose signal source. The signal source in a KHz- 10MHz range stability can be adjustable output sine wave, with AM, FM, ASK and other PSK modulation functions. Part of the output signals using low loss current-feedback operational amplifier for wideband voltage amplification and very good solution with the bandwidth and load capacity requirements. Chinese system with display and keyboard control functions, simple operation, achieving good results. Intron original program, sinusoidal signal generator pCB diagram, and a number of related papers.
