Abstract :
This paper presents the mathematical theory and practical difficulties involved in the adaptation of the quadrant electrometer to radio-frequency power measurements. Two modified electrostatic wattmeter circuits are described and the limitations in their use are given. Data on typical measurements between 20 and 150 watts at 655 kilocycles are presented with the corresponding degree of accuracy for each case.
