Design and Testing of NFRad - A New Noise Measurement System

Published

Chriss A. Grosvenor, James P. Randa, Robert L. Billinger

Abstract

The NIST Noise project has constructed and tested a new, automated, coaxial (GPC-7) radiometer for the measurement of noise sources in the 8-12 GHz frequency band. It is an isolated, total-power radiometer that relies on lookup tables for relevant reflection coefficients and path asymmetry. This permits measurements at multiple frequencies much more quickly than on previous NIST systems. This paper reviews the theory, describes the design of the system and its components, and details the testing procedures and the operation of the system.
