The noisefactor analyzer's operation principle and the basic noisefactor measurement method, Y factor method, are described.
论述了噪声系数分析仪的工作原理和噪声系数最基本的测量方法——Y因子法。

In the meanwhile, with using more accurate expression of the avalanche excess noisefactor, we give a relation schema between sensitivity and dark current.
同时，采用了较为精确的过剩噪声系数表达式，给出了灵敏度与暗电流的关系曲线。

But there's another important factor in this process: background noise.
