内容記述 | To improve stability of a radiometer, we must first design the equipment so as to reduce the influence of variations in modulation frequency as well as in local frequency. All power supplies should then be kept constant within 0.1%. Substitution error is apt to be the main cause of incorrect calibration, which can be reduced remarkably by applying a new simple method of extending the h-f circuit. Two applications of Faraday rotation are suggested in reducing substitution error and in the static modulation. A high modulation frequency which may be obtained from the latter application will reduce fluctuations on the record. In completing calibration curves, it is preferable to use magic tees as the attenuator. | |||||
