Time Domain Measurements using Vector Network Analyzer R&S®ZVR

Vector Network Analyzers of the ZVR family measure magnitude and phase of complex S-parameters of a device under test (DUT) in the frequency domain. Using an inverse Fourier transform, the results can be transformed to the time domain. The impulse or step response of the DUT is obtained, which gives an especially clear representation of its characteristics. For instance, faults in cables can be directly localized. Moreover, special time domain filters, so-called gates, can be used to suppress unwanted signal components such as multireflections.
