The power equation concept has been implemented into a multioctave precision bolometer unit calibration system employing automation techniques in conjunction with an automatic network analyzer (ANA) system. Using statistical methods the system is being evaluated as a calibration transfer system operating in the 2-12.4-GHz frequency range at 1-10 mW. preliminary results reported here show a single measurement standard deviation of 0.2-1 percent from 2-10 GHz. Upon a successful evaluation, the system will be qualified as an integral part of the national measurement system.
