AM和PM噪声测量的初步校准
Primary calibration of AM and PM noise measurements
摘要：
本文介绍了相位噪声和幅度噪声测量系统的一次校准方法。在计量学领域，“一级”是指一个标准，其量值和测量不确定度的建立与同类量的另一个测量标准无关;或者是指用于实现测量单位的定义并获得一级测量标准的量值和测量不确定度的程序。因此，相位和归一化幅度必须依赖于比率测量。
英文摘要：
This report describes a method for the primary calibration of phase noise and amplitude noise measurement systems. In the field of metrology, the term "primary" refers to a standard whose quantity value and measurement uncertainty are established without relation to another measurement standard for a quantity of the same kind; or to a procedure used to realize the definition of a measurement unit and obtain the quantity value and measurement uncertainty of a primary measurement standard. Accordingly, a phase and a normalized amplitude have to rely on ratio measurements.
