摘要
采用频谱仪作为核心测量设备,结合虚拟仪器技术和电磁辐射测量理论,研究电磁辐射自动测量的工程实现方案,并开发相应的监测分析软件,实现电磁辐射的自动测量。以Agilent E4445A频谱仪为基础组成选频式电磁辐射自动测量系统,可实现所选频率信号瞬时场强、带宽信号平均综合场强等量值的自动测量,通过软件分析可得到多种环境污染图。其自动测量分析内容和测量误差符合相关行业标准。
To automatically measure electromagnetic radiation with a spectrum analyzer as the key measuring equipment,the engineering realization plan is studied and corresponding software is developed with virtual instrument technology and electromagnetic radiation measurement theory.The frequency-selecting automatic measuring system of electromagnetic radiation using Agilent E4445 A spectrum analyzer is designed,which is able to automatically measure instantaneous electric field and average comprehensive electric field of bandwidth signal etc.The analysis software may produce kinds of environment pollution graphs.And the automatic measurement contents and error accord with relative industry standards.
