摘　　要：电场探头是电磁辐射测量的关键仪表,为了保证测量结果的准确性,需要定期校准探头。依据IEEE 1309-2013规定的电场探头校准方法,中国信息通信研究院泰尔终端实验室搭建了频率范围9 kHz~40 GHz,场强范围0.5~800 V/m的电场探头自动化校准系统。利用系统对两款不同频段和场强范围的电场探头进行了校准,频率响应、场强和各向同性的校准结果证明了校准系统的可行性。系统校准能力获得CNAS(中国合格评定国家认可委员会)及NVLAP(美国国家实验室自愿认可程序)认可。Electric field probe is the key instrument for measurement of electromagnetic radiation.In order to ensure the accuracy of measurement results,it is necessary to calibrate the probe regularly.According to the electric field probe calibration method specified in IEEE 1309-2013,China Academy of Information and Communications Technology,Telecommunications Technology Lab has set up an automatic calibration system for electric field probe covering the frequency range of 9 kHz to 40 GHz and the field intensity range of 0.5~800 V/m.Two electric field probes with different frequency bands and field strength ranges are calibrated by the system.The calibration results of frequency response,field intensity and isotropic parameters prove the feasibility of the calibration system.The system calibration capability is accredited by CNAS(China National Accreditation Service for Conformity Assessment)and NVLAP(National Voluntary Laboratory Accreditation Program).
