| Abstract: | 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. |
