Abstract
The effect of receiver saturation is examined for a total power radiometer which uses an ambient load for calibration. Extension to other calibration schemes is indicated. The analysis shows that a monotonic receiver saturation characteristic could cause either positive or negative measurement errors, with polarity depending upon operating conditions. A realistic model of the receiver is made using a linear-cubic voltage transfer characteristic. The evaluation of measurement error for this model then provides a means for correcting radio source measurements. It also provides the means for assuring that this source of error is small in a particular situation.
