A Method of Measuring Small Radio-Frequency Powers

Abstract

The sensitivity of the standard bolometer bridge circuit is increased ten-fold by switching between a standard and unknown power at the resonant frequency of the indicating galvanometer, This technique has the advantage of reducing the masking effects due to drifts in ambient temperature and supply voltages for the bridge circuit. Powers may be measured to one microwatt and below.
