一、前言微波功率的测量和校准是一项既费力又费时间的工作。目前使用的方法需将标准和被测装置交替接至一个稳定的微波源上。此外,通常还需要在每一测量频率上对源进行调配,以减小失配误差。本文所描述的方法是采用一个量热计作参考标准来自动校准通过式功率传递标准,再用功率传递标准来校准终端功率传感 I. Introduction Microwave power measurement and calibration is a laborious and time-consuming task. The current method is to alternate the standard and the device under test to a stable microwave source. In addition, it is often necessary to source the source at each measurement frequency to reduce mismatch errors. The method described in this article uses a calorimeter as a reference to automatically calibrate the pass-by-pass power transfer standard and then the power transfer standard to calibrate the terminal power-sensing
