The multi - port measurement system has the widespread use in microwave measurement, the measurement of multi - port device with two - port vector network analyzer ( vna ) is researched. this paper analyzes the commonly used error models and calibration methods of vna, program a trl calibration procedure for two - port vna, and compare the tested data with the data from vna. the comparison show that the programmed trl calibration procedure is in the same accuracy as the vna
本文討論了兩埠矢量網路分析儀常用的誤差模型和校準方法，編制了兩埠矢量網路分析儀基於trl校準法的校準程序，並把校準后的測量結果和矢量網路分析儀校準后的測量數據做了比較，比較結果說明編制的trl校準程序校準效果和矢量網路分析儀校準的效果相同。 -
The measure system is based on virtual instrument technology. its hardware includes measurement flat, servo motor, vector network analyzer ( vna ) etc. and its software is programmed by labview
測量系統採用虛擬儀器的設計思想，由測量平臺、伺服電機、矢量網路分析儀、計算機等硬體組成，用labview完成了系統軟體設計。 -
We also discuss the design of cavity that is used in experiment 、 means for how to stir electromagnetic wave and choice of diameter / length ratio for cavity. final, we have made an experiment to cigarette with apparatus made up of vector network analyzer ( vna ) and cavity that is designed by ourselves, regressed the equation with matlab software, analyzed measurement errors, put forward some means that reduce measuring error
最後，使用自己設計的諧振腔和矢量網路分析儀搭成的實驗裝置對卷煙進行了密度測量實驗研究，並用matlab軟體對測量數據進行了回歸擬合，建立了密度測量的方程，並對測量誤差作了分析，提出了進一步減小誤差的途徑。
