本文主要介绍的是DDS信号源的组成及其工作原理。在现实生活中DDS信号源的用处非常的大。尤其是在关于电路方面的实验中,很多的电路实验中都需要信号发生器,而DDS信号发生器就是一个不错的选择。因为在有些实验中要求的波形不同,所以要求设备能提供不同的输出波形用于选择。DSS信号源模块硬件上由CM3(cortex-m3)内核的ARM芯片(STM32)和外围电路构成。在我们实验室中的RZ8681D试验箱的DDS信号源能够输出多种波形,用起来非常的方便与快捷。
This article mainly introduces the composition of DDS signal source and its working principle. The usefulness of DDS sources in real life is very large. Especially in the circuit experiments, a lot of circuit experiments require signal generator, and DDS signal generator is a good choice. Because of the different waveforms required in some experiments, the device is required to provide different output waveforms for selection. DSS source module hardware by the CM3 (cortex-m3) core ARM chip (STM32) and peripheral circuits. The DDS signal source in our RZ8681D chamber is capable of outputting a wide range of waveforms for ease and speed of use.
