Description: 本文主要介绍的是采用直接数字频率合成的短波信号发生器，它主要以微电脑控制部分、直接数字频率合成（DDS）部分、数字锁相环频率合成部分、背光液晶显示部分、功率放大部分等组成。该软件系统采用菜单形式进行操作，操作方便明了，增加了很多功能。它通过启动DDS后，把内存缓存区的数据送到DDS后输出相应的频率，并把数据转换为BCD码，送到液晶显示器进行显示。该系统输出稳定度、精度极高，适用于当代的尖端的通信系统和精密的高精度仪器。-This paper describes the use of direct digital frequency synthesis of short-wave signal generator, which is part of a micro-computer control, Direct Digital Synthesis (DDS) of the digital part of PLL frequency synthesizer, backlit liquid crystal display of the power amplifier, etc. composition. The menu system uses the form of software to operate, easy to operate and clear, increase in the number of features. DDS through start after the memory cache after the data to the DDS output corresponding frequency, and the data is converted to BCD code to the LCD display. The output of the system stability, high precision for cutting-edge contemporary and sophisticated communication systems high-precision instruments Platform: |
