The measure method research regarding attenuator of basic high-powered level

Concerning the method, the attenuator of high power will normally be measured through low power, will bring about big error to the measurement of high powered level. For the purpose of improving the accuracy of measurement, this article set out the measure method of attenuator through high power. Such method can infer the functional relation of decrement based upon the analysis of the rule as to the decrement of attenuator under the change of temperature and power level. Measuring the attenuation of a high power attenuator in this way and the error of measurement is discussed.
