Abstract
The IF attenuator normally used for system noise temperature calibrations is the largest single contributor to measurement inaccuracy. Various IF attenuators have been evaluated and calibrated using a National Bureau of Standards IF precision standard. Measurement techniques are indicated and results given. It is noted that there is a wide spread in the accuracy among various manufacturers and also in the same model type from a particular manufacturer. Excessive use appears to be an important factor in accuracy degradation.
