基于GPIB总线的电磁环境自动化测试系统

Automatic Electromagnetic Environment Test System Based on GPIB Bus

针对电磁环境测试工作中存在的实际问题,提出基于GPIB总线的电磁环境自动化测试系统的解决方案。电磁环境自动化测试系统由计算机上运行的自动化测试软件通过GPIB接口卡和GPIB电缆控制EMI接收机和不同频段的测试天线,实现分频段电磁环境测试,自动处理测试数据和生成测试报告。系统分为参数设置、测试控制、数据处理、频谱显示、测试报告、数据保存和数据载入等主要模块,文中给出了每个模块的详细设计。

For the purpose of electromagnetic environment test, an efficient solution based on GPIB bus is proposed. The GPIB-based automatic test system would realize the implementation of electromagnetic environment test,with EMI analyzer and antennas controlled by software on computer through GPIB card and GPIB cables. The results are analyzed and treated automatically, and subsequently a report with data and spectrum graph can be formed by software. Details of the system modules are available in the paper.
