摘要

本文详细分析了基于冷源的噪声系数测量在频谱分析仪中的适用性。在处理与设备输入匹配相关的问题时，与传统的y因子技术相比，该技术具有一些优势。分析了一个完全校正的噪声系数计算程序，并辅以矢量校正和接收机噪声校准。为此，给出了一种基于解析计算的频谱分析仪接收机的噪声标定方法。

Cold-source measurements for noise figure calculation in spectrum analyzers

A detailed analysis of the suitability of cold source based noise figure measurements in a spectrum analyzer is given in this paper. This technique presents some advantages in comparison to classical Y-factor techniques when dealing with problems related to device input match. A fully corrected noise figure calculation procedure, complemented with vector corrections and receiver noise calibration, is analyzed. For that, a noise calibration of the spectrum analyzer receiver, based upon analytical calculation, is given.
