R&S ZNA50 and R&S ZNA67 Vector Network Analyzers

The R&S ZNA high-end vector network analyzer (VNA) now features models with 50 GHz and 67 GHz maximum frequencies. This opens up the VNA’s RF performance, hardware concept, and innovative touch operation to new areas of application. Signal integrity measurements as well as A&D and 5G component and module characterization are main applications for the new analyzer models.

The R&S ZNA includes wide dynamic range, extremely low trace noise, and a user-friendly, purely touch based GUI. Its hardware platform offers up to four internal, phase coherent sources. There is also fifth source which can be used as a second internal local oscillator or as an additional source for measurements on mixers. In combination with up to eight truly parallel measurement receivers, the hardware architecture is ideal for demanding measurements on components and modules.

The new models offer opportunities for the aerospace and defense industry by enabling characterization of radar and transmitter/receiver modules as well as performing antenna measurements and supporting satellite applications such as downconverter characterization. They also offer versatile capabilities for both pulse generation and measurement, including a wide range of trigger functions. Since the analyzer’s original introduction, updates have added new features such as direct source monitor access that enables accurate measurements even on high gain devices.

In combination with integrated deembedding solutions (ISD, SFD, DELTA-L and EZD), the R&S ZNA provides characterization of PCB conductor structures for high-speed signal transmission. The effects of fixtures, lead-ins, and lead-outs are removed from the measurement results.
