摘要
给出了一种基于MSP430单片机,通过按键控制对高频信号进行数据采集和液晶显示,实现采集显示的系统。该系统以MSP430单片机为核心,由自动控制模块、待测信号锁相环路模块、按键控制模块、信号采集及数据显示模块几部分组成。从实验结果来看,该系统能够控制产生稳定的高频信号、完成从950 MHz^2.15GHz频率的扫频、信号自动采集以及显示屏上对数据的实时显示,具有很好的市场应用前景,也具有很高的兼容性。该测试系统搭建简单方便、具有精度高、性能稳定、价格低廉等特点。
This paper presents a system about high-frequency signal based on MSP430 MCU for data collection and LCD display.MSP430 is as the core of the system,composed of several parts,the automatic control module,the test signal phase-locked loop module,key control module,signal acquisition and data display module.From the experimental results,the system can control the generation of stable high frequency signals from 950 MHz to 2.15 GHz frequency to complete the sweep,the signal be collected automatically and displayed on the screen in real time.The system has good market prospects and high compatibility,it is simple and convenient,also has the advantage of high precision,stable performance,low price and so on.
