摘要
为了使射频阻抗测试仪器在对元器件进行测试时能获得准确可靠的测试结果,测试前必须对仪器进行校准,消除不确定因素对测试结果的影响.射频阻抗标准器组件可使测试仪器内部存储的基准数据能够和国家阻抗基准建立溯源关系.本文对标准器组件中的开路阻抗标准器进行分析,通过理论计算和实际测量相结合,采用等效法及全频段插值计算法完成开路器的量值定标.
In order to get accurate and reliable parameters for the electronic components by the RFimpedance measuring instrument, the instrument must be calibrated to eliminate the uncertainties inadvance. RF impedance standard kit plays such a role that can establish traceability relationship be-tween the internal memory storage data of measuring instrument and national impedance reference.Herein, this study focuses on the theoretical analysis of the open impedance standard, which is one ofthe RF impedance standard kits. Theoretical calculation and measurement is adopted in this paper.The calibration of the open standard is finally accomplished with the equivalent method and interpola-tion method.
