摘要
使用空气波导和TEM小室测试得到电场探头的频率响应数据,并与已溯源的标准场数据进行比较,分析了在自由空间环境中电场探头的频率响应及校准中的不确定度。结果表明,使用标准波导和TEM小室校准电场探头在自由空间环境中的频率响应的方法是可行的。
The frequency response data of E-field probe are obtained based on the air waveguide and TEM cell testing method. Comparing the frequency response data with the traceable standard field data, the frequency response of electric field probe and the uncertainty of calibration in free space environment are analyzed. The result indicates that the method is feasible to use standard waveguide and TEM cell to calibrate electric field probe in free space environment.
