摘　　要：根据IEC 61000-4-20:2010,介绍了场均匀校准的要求和方法,结合电磁波的传播特点并基于概率统计的方法对GTEM Cell中选定的有效试验区域进行验证;同时,针对试验结果,用GB 17626.3-2006暗室的场均匀校准方法重新验证。最后分析测试结果,并提出相应建议。Field uniformity is an important indicator to assess the GTEM cell, the requirements and methods of field nniformity calibration in IEC 61000-4-20：2010 were introduced. Combining with the characteristics of electromagnetic wave propagation, the field uniformity was calibrated based on probability statistics methods according to the mentioned requirements and methods. Meanwhile, by analysis of test results, another field uniformity ealibralion has been done according to GB 17626.3-2006. Corresponding recommendations was also proposed.
