资用噪声功率即等效输出噪声温度是热噪声标准源的一个关键技术指标,其是匹配负载终端和有耗传输线噪声贡献的合成.为减小等效输出噪声温度的计算复杂度,采用了多项式拟合后分段叠代计算的方法,并分析了有限温度测量点的情况下,不同分段数对计算结果的影响.

Available noise power or equivalent output thermal noise temperature is a key specification for standard thermal noise source. It is a combination of the noise contribution of matched termination and lossy transmission-line. In order to simplify the calculation of equivalent output thermal noise temperature, polynomial curve fitting and iteration methods are involved. The affection of segment number is also discussed.
