Vector Network Analyzers of Rohde&Schwarz family are able to measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. By means of the inverse Fourier transform the measurement results can be transformed to the time domain. Thus, the impulse or step response of the DUT...
