Abstract
In this paper, it focus on the need for setting up a virtual vector network analyzer (VNA), which only has frequency-domain measurement technology. The software model is presented and many simulations are performed within the Lab view software. Using the chirp-Z and inversing chirp-Z transform, after the window function and gating function processed it gets the frequency response, which removes what it does not want, such as impedance discontinuity. A very good agreement among the results of the proposed technique, results available in the literature [1], and experimental results is observed. At the end of the paper, the practical measurement results and late transform results are given. It easily proves that the results are closer to the true parameters of the Device under Test (DUT).
