一、引言众所周知,测量线本身存在的误差源包含有线体的剩余反射、机械不平稳度、探针的加载效应、线体衰减及探针位置的测量误差等五项。在测量线检定中一般给出前三项,后两项通常予以忽略。不过在实际使用中只能给出误差(或合成误差),而不能给出校正值。本文设想利用校正网络法对测量线精确校正。 I. INTRODUCTION It is well known that the sources of error in the measuring line itself include the remaining reflection of the wired body, the mechanical unevenness, the loading effect of the probe, the attenuation of the line body and the measurement error of the probe position. In the measurement line test is generally given the first three, the latter two are usually ignored. However, in actual use only gives the error (or synthetic error), but can not give the correction value. This paper envisages the use of calibration network method to accurately calibrate the measuring line.
