Abstract:

The United Kingdom national standards for power in waveguide consist of bolometer mounts of known efficiency at discrete frequencies from 8.2 GHz to 35 GHz. This report outlines recent developments in the design, construction, calibration and use of the standards. An analysis of random and systematic uncertainties in the microcalorimeter method of calibration forms a significant part of the report and yields an overall uncertainty of or - 0.1 in the mount efficiency with 95 confidence. Features of a technique for calibrating power meters in terms of a bolometer standard using a waveguide transfer instrument are described together with an analysis of uncertainty in the technique. Comparisons in the past five years of the RSRE developed standards with other power standards are also summarised. Author
