摘要
给出了一种基于CH376实现MSP430单片机对实验室小型天线信号采集存储的系统。由于工程测试的需要设计开发了天线方向图自动测试系统。该系统以MSP430单片机为核心,由自动控制模块、信号采集和数据显示模块和USB主机方式数据存储模块三部分组成。从实验结果来看,该系统能够实现转台的自动控制、信号的自动采集、天线方向图的自动绘制和数据实时存储到U盘。测试平台搭建方便,具有测试速度快、精度高、性能稳定的特点。
This paper introduces a design scheme which MSP430 single chip collect and store the signal that is the laboratory small-size antenna base on the USB interface chip CH376. According to the engineering measure needs,I want to design an automatic measurement system of antenna radiation pattern. The system as MSP430 MCU to the core, constitutes by three parts of the automatic control module, signal acquisition and data display module, data storage module of USB host mode. For the experiment results, this system can realize the automatic control of rotary table, automatic data acquisition, automatic draw of antenna pattern and real-time data is stored in the U disk.The system has the quality of high accuracy, high testing velocity and high reliability.
