本文讨论了需要测量的低温噪声参数。讨论了测量过程，并对测量不确定度进行了分析。为了验证正确的操作的测量系统，测量1至2 GHz的射电天文低噪声放大器（LNA）在20，75，和296 K。在这些测量中，噪声温度和最小噪声温度的典型1σ测量不确定度<10%。
This paper addresses the need for measured cryogenic noise parameters. The measurement process is discussed and an analysis of the measurement uncertainty is performed. To verify proper operation of the measurement system, measurements of a 1-to-2-GHz radio-astronomy low-noise amplifier (LNA) at 20, 75, and 296 K are presented. In these measurements, the typical 1σ measurement uncertainty in noise temperatures and minimum noise temperatures is < 10%.
