Network Analyzer Calibration Using Short Lengths of Precision Transmission Line

Abstract

The techniques for the calibration of a microwave network analyzer have been developed largely on the basis of the use of a number of devices (standards) to determine the terms of the system error model. This paper discusses techniques which employs only one component the properties of which determine the quality of the error corrected results. The component is an electrically short length of transmission line which, although theoretically desirable, is difficult to manufacture and connect. The paper describes the design and construction of such a structure and demonstrates its use in obtaining significantly improved error correction when used in conjunction with an HP 8510 network analyzer.
