Transparent full-two port network analyser for microwave lab courses

摘要

In this paper a measurement device is presented which has been developed only for lab courses in RF technology. In a student's thesis work a transparent network analyzer was developed, which has been assembled with different Rohde & Schwarz vector voltmeters devices of older age. The objective is to measure the scattering parameters of a device under test vividly for students. The RF circuitry controlling the port excitation is placed in a box which is accessible by students for educational purposes. The whole measurement is controlled and analyzed by MATLAB.
