Rohde and Schwarz ZNL-K2 - Time Domain Analysis Option for ZNL/ZNLE

The R&S ZNL/ZNLE offers powerful time domain analysis (R&S ZNL-K2 option) to measure components such as filters and high-speed digital data cables in the frequency and time domain.

The network analyzer measures and displays complex S-parameters and other quantities as a function of the frequency. The measurement results can be filtered and mathematically transformed to obtain the time domain representation, which often gives a clearer insight into the characteristics of the DUT.

Time domain transforms can be calculated in band pass or low pass mode. For the latter, the analyzer offers the impulse and step response as two alternative transformation types. A wide selection of windows can be used to optimize the time domain response and suppress side lobes due to the finite sweep range. Moreover, it is possible to eliminate unwanted responses using a time gate and transform the gated result back into the frequency domain.
