一、前言射频和微波功率测量易受种种误差源影响,这些误差源起因于:(1)处理功率传感器输出电压所用电路与技术的局限性,通常称为仪器误差,它与频率无关;(2)传感器校准误差;(3)信号源与传感器阻抗不一致引起的失
I. INTRODUCTION Radio frequency and microwave power measurements are susceptible to various sources of error. These sources of error result from: (1) the limitations of circuitry and techniques used to process the power sensor output voltage, commonly referred to as instrumental errors, which are frequency independent; (2) ) Sensor calibration error; (3) signal source and sensor impedance caused by inconsistencies
