摘　　要：针对IEC61000-4-3标准的要求,提出了一种新的利用LabVIEW软件开发环境构建电能表射频电磁场抗扰度测试系统的方法。明确了系统的软硬件组成,分析了闭环校准、扫频测试、点频测试3个主要测试模块,给出了测试流程图和主要界面,分析了设备连接和数据趋近算法2项关键技术。由于LabVIEW的开放性,该系统只需进行简单的修改,可以应用于不同的测试要求和仪器配置中去。According to the requirement oflEC 61000-4-3 standard, a new method using LabVIEW to build test system of watt-hour meter radio-frequency electromagnetic field immunity was proposed. The system＇s hardware and software compositions were nailed down. The three main testing modules like closed-loop calibration, frequency sweep test and dot frequency test were analyzed. The testing flowchart and the main interface were given. The equipment connection and the data convergence algorithm were analyzed. Because of the openness of LabV1EW program, this system is applicable to different test requirements with its parameters or programs adjusted.
