    Nyckelord :Time-domain analysis; Chirp z-transform; Kaiser-Bessel window; Filtering in time domain; Effects of time-domain analysis; Reverse engineering; De-embedding; TRL algorithm; uncertainties; sensitivity;

    Sammanfattning : Time domain analysis in vector network analyzers (VNAs) is a method to represent the frequency response, stated by the S-parameters, in time domain with apparent high resolution. Among other utilities time domain option from Agilent allows to measure microwave devices into a specific frequency range and down till DC as well with the two time domain mode: band-pass and low-pass mode.
