In this talk, one of the most complicated and important measurement equipment called – Vector Network Analyzer –, used in almost every RF test laboratory and many manufacturing processes for RF devices is explained. With help of a general block diagram, the typical hardware components which can be found in commercial VNAs, are described. In the next step, the measurement principle for obtaining the well-known S-parameters is discussed. Afterward, the speaker points out the main measured quantities by a vector network analyzer which RF engineers in the industry should be able to apply for the design of RF components and their validation using circuit simulation tools. The need of the VNA calibration and the common calibration methods implemented in the commercial VNAs are explained in the last step. The lecture finishes with some advices for low-cost / less precise VNAs suitable for education purposes in technical schools and universities.
