Realization and Dissemination of High Frequency Power Standard at INRIM.

In the High Frequency (HF) field, the primary power standard is maintained through reference sensors calibrated in terms of effective efficiency ge. These devices are in turn used to transfer the power standard by means of direct comparison on the same matched generator. For this kind of operation, the only knowledge of the effective efficiency of the device is not enough and additional parameters of the reference sensor are necessary. The paper describes the methods and techniques used at INRIM to disseminate the ‘‘HF power standard’’, with emphasis to all the technical aspects involved, in order to provide a thorough explanation of the procedures implemented.
