2技术报告(ETR 028)中的测量不确定度的计算方法,介绍了通用计算、特殊计算等内容。本期将通过一个具体的实例,详细地给出某项无线电指标测量中的评定过程,加深读者对相关计算公式的理解及运用。 不确定度计算的详细步骤 以测量载波功率项目为例。已知发射机的载波功率 2 Technical Report (ETR 028) in the calculation of measurement uncertainty, introduced the general calculation, special calculations and so on. In this issue, we will give a detailed example of the evaluation process of a radio index measurement through a concrete example and deepen the reader’s understanding and application of the relevant calculation formulas. The detailed steps for calculating the uncertainty are based on measuring the power of a carrier. The transmitter’s carrier power is known
