摘　　要：基于感应电压叠加器感应腔角向传输线电流探头离线标定的需求,设计了离线标定平台。离线标定平台为平板传输线结构,与在线标定相比,对标定信号的畸变更低。分析了跨平台标定误差的来源,并针对性提出降低误差的措施。分析表明,安装偏心及探头纵向安装深度是跨平台标定误差的最大来源,需要在工程设计中重点关注。实际建立了离线标定平台并开展误差分析,得到跨平台标定误差3.3%的结果。An off-line calibration platform is designed based on the requirement of off-line calibration of induction cavity azimuthal transmission line current probe.The analog device is a flat-plate transmission line structure,which has lower distortion than on-line calibration.The source of cross-platform calibration error is analyzed,and the measures to reduce the error are put forward.The analysis shows that the installation eccentricity and probe longitudinal installation depth are the biggest sources of cross-platform calibration error,which need to be paid attention to in engineering design.An off-line calibration platform is established and the error analysis is carried out.As a result,3.3%cross-platform calibration error is obtained.
