Abstract
The X-band attenuation is compared with that of a calibrated 30-Mc reference attenuator by means of a linear superheterodyne detector. Estimated accuracy is ±(0.010 db+0.005 db/10 db) for a dynamic range of 40 db. Frequency control of the signal and local oscillator klystrons, stabilization of the signal power level, and use of a stable IF amplifier have resulted in a drift for the standard of less than ±0.005 db per five-minute interval.
