VNA operates up to 67GHz
The R&S ZNA high-end vector network analyzer (VNA) now features models with 50 GHz and 67 GHz maximum frequencies.

Rohde & Schwarz has launched a vector network analyzer (VNA) with a frequency range up to 67GHz.

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 outstanding RF performance, unique 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 has wide dynamic range and extremely low trace noise, and comes with a user-friendly, purely touch based GUI. The hardware platform offers up to four internal, phase coherent sources plus a 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 R&S ZNA hardware architecture is ideal for demanding measurements on components and modules.

The R&S ZNA is aimed at engineers working on tasks such as high-end research and development. The 50 GHz and 67 GHz frequency range helps 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 two years ago, updates have added new features such as direct source monitor access, which enables accurate measurements even on high gain devices such as satellite downconverters.

High-end R&D signal integrity measurements on differential lines up to 67 GHz, and can be combined with Rohde & Schwarz mmWave converters. Using integrated deembedding solutions (ISD, SFD, DELTA-L and EZD), the R&S ZNA provides characterization of PCB conductor structures for high-speed signal transmission where the effects of fixtures, lead-ins and lead-outs are removed from the measurement results.

Covering the 5G frequency bands and, in combination with Rohde & Schwarz mmWave converters, the
