The R&S ZVK (1127.8651.60) 40 GHz Network Analyzer is a compact instrument with an integrated generator, two reference and two receiver channels and a bidirectional test set. This can be extended by attenuators with integrated switches in the generator and receiver paths. With this configuration, the ZVK offers direct access to all reference and receiver channels. This concept makes the ZVK well equipped for complex test setups, for example for bidirectional measurements on power amplifiers. The ZVK has two independent synthesizers for the generator and the receiver. In the receiver sections, fundamental mixing is used up to high frequencies to provide the excellent dynamic range and outstanding selectivity, enabling straightforward measurements on frequency-converting DUTs or DUTs with extremely high selectivity. By transforming measurement data from the frequency to the time domain, discontinuities or impedances along the DUT can be displayed as a function of DUT length. With a maximum number of 2001 points, ZVM and ZVK can measure even very long DUTs with high resolution. Five filters allow the location of a discontinuity and the sidelobe suppression to be determined with optimum resolution. The S-parameters of a given discontinuity can be displayed in the time domain by setting a window (gating). An additional processor module included in the corresponding option accelerates data processing and the display of results to provide even realtime display – a valuable aid, for example in the tuning of bandpass filters with time domain transformation.
