摘　　要：对电流探头进行校准,准确地将探头的转换因子定标,是保证EMC检测中多个项目质量的必要条件。在对EM I电流探头的现状进行介绍的基础上,提出了用微波网络分析仪校准电流探头的方法。该方法具有准确、便捷及自动描绘结果曲线的优点。Calibrating the EMI current sensor and accurately determining conversion factor of the sensor are the necessary conditions for ensuring the quality of multiple items in EMC test. This paper, on the basis of describing the present status of the EMI current sensor, brings forward a method of calibrating EMI current sensor with the microwave network analyser, which features the advantages of accuracy, convenience and automatically plotting the result curve.
