摘　　要：GJB 151B-2013规定了电场辐射发射测试系统的校验配置,该配置对测量接收机、测试软件和连接电缆进行校验,但未考虑接收天线和周边电磁环境对测试结果的影响。标准测试步骤中虽有补正要求,但不易落地操作。文章基于GB/T 18655-2018“长线天线建模法”的理论基础,精简其公式、自制50 cm发射天线升级梳状信号源,模拟“长线法”的辐射源。以10 kHz~30 MHz点检应用为例,改进RE102测试系统校验方案替代原校验配置。该方法可以及时发现测试系统可能存在的问题,有效保证辐射发射测试系统的准确性和稳定性。GJB 151B-2013 specifies the calibration configuration of the electric field emission test system,which verifies the measurement receiver,test software,and connection cable.However,the influence of the receiving antenna and the surrounding electromagnetic environment on the test results is not considered.Although there are correction requirements in the test steps of the standard post text,it is not easy to implement the operation.Based on the theoretical basis of GB/T 18655-2018"Modelled long wire antenna method",this paper simplified its formula and upgraded the comb signal source of 50 cm transmitting antenna to simulate the radiation source of"long-line method".Taking 10 kHz~30 MHz spot check application as an example,the calibration scheme of RE102 test system is improved to replace the original calibration configuration..Through the method given in this paper,possible problems can be found in time,and the accuracy and stability of the radiation emission test system can be effectively guaranteed.
