【摘要】 本文系作者研制的"螺旋线慢波结构冷特性自动测量系统"的补充,给出了此类系统测量误差的详细理论分析,并对典型数据进行了计算。结果表明色散特性(相光速比)的测量误差可小于0.5%,基波耦合阻抗的测量误差则可达15%。更多还原

【Abstract】 The error analysis of the automatic measurement system of the cold parameters of the slow wave structure of the helix TWT is completed in this paper.The detailed theoretic analysis of measurement errors is provided and the typical data of the parameters are applied.The results show that the error of the dispersion measurement is less than 0.5% and the error of the interaction impedance measurement is less than 15%.更多还原
