摘　　要：针对现有衰减校准系统量程小、难以满足步进衰减器等大衰减量计量需求的问题,通过对T矩阵法的分析研究,提出了利用T矩阵法实现非程控步进衰减器测量的方案,详细介绍了T矩阵法的原理和实现过程,经过实测验证,所述方法可为大衰减量的计量测试提供一套切实可行的解决方案。The range of current attenuation calibrating system is too small to meet the requirement of calibration of step attenuator with high attenuation value.Based on the analysis of the T-matrix method,a new measurement scheme is proposed to measure nonprogrammable step attenuator with high value.The principle and implementation process of T-matrix method are detailed.It is proved to be feasible by the actual test.It can be a set of practical solutions to the calibration of attenuation with high value.
