Analysis of testing error virtual test System;

虚拟测试系统的测试误差分析

The conclusion is obtained that the test result satisfies the test error request.

分析方形四探针探针游移对其测量微区薄层电阻的影响,完成了测试薄层电阻的公式的推导,对游移后产生的误差影响进行了统计数据分析,得出了测试结果满足测试误差要求的结论。

This article presented the remote fiber testing system (RFTS) in terms of its structure, test methods and integration with the telecommunication management network (TMN),gave several typical RFTS in order to explain its application and development trend, lastly, discussed the factors affecting the test accuracy of OTDR as well as the measures to solve the test errors.

同时 ,还讨论了影响光时域反射仪 ( OTDR)测试精度的要素和消除测试误差通常采用的对策 。

Although calculation method for proportion is various,the error method in common use takes a lot of trouble.

配料计算虽方法繁多,但常用的尝试误差法计算费时费力。
