Analysis of the Uncertainty of Microwave Yawp Standard System

Zhou Hongwei Li Feng (Technology Mechatronics Automation School of National University of Defense, Changsha 410073)  
The Microwave Yawp Standard System consist of 7009 hot/cold yawp temperature signal generator, 1350 series mixer, 13680 low yawp preamplifier, 13611 precision receive machine and two frequency synthetical generator. The paper analysed the uncertainty of sort A and sort B of the microwave yawp standard system from hot yawp output yawp temperature signal generator, cold yawp output yawp temperature signal generator, Y reading, mismatch. Furthermore, It analysed the value?s extend uncertainty when value is transferring, and the uncertainty when the solid yawp signal generator was being compared.
