Abstract
A direct comparison power measurement system has been developed to measure power sensor effective efficiency in the 100 kHz to 18 GHz frequency range. This system is capable of measuring thermistor and thermoelectric based power sensors. Several problems needed to be addressed in the development of the system. These included rf leakage through the power sensors and its effect on system electronics; power meter and digital volt meter sensitivity to extraneous signals; and the effect of comparison beads, if there were any, int he sensors. The system design, discussion of the mose important problems, the uncertainty analysis for the system and comparison to measurments made by the NISt 0.05 GHz to 50 GHz system and the voltage/impedance technique will be covered.Citation
