Rohde & Schwarz: VNAs with multiport architecture for measurements from 100 kHz to 40 GHz

The new R&S ZNBT40 from Rohde & Schwarz is the first vector network analyzer (VNA) with a broad frequency range from 100 kHz to 40 GHz and up to 24 integrated test ports. Developers can use it for applications such as measurements on 5G antenna arrays. The multiport architecture is not only advantageous for tests on multiport components, but also for simultaneous testing of multiple DUTs in production to boost throughput. Rohde & Schwarz ensures specified performance on up to 24 test ports with the R&S ZNBT40. Also new is the R&S ZNBT26 for measurements up to 26.5 GHz.

Thanks to its frequency range up to 40 GHz, manufacturers of active and passive components can use the new R&S ZNBT40 vector network analyzer for a wide variety of multi-antenna communications systems (MIMO, SISO, MISO), including radar systems for the A&D sector. It is perfect for measurements on frontend modules, antenna arrays and beamformer chips for 5G NR. It measures up to 24 test ports at the same time, enabling measurements on multiport components as well as simultaneous parallel measurements on multiple DUTs.

The R&S ZNBT is currently the only multiport vector network analyzer that can measure in the frequency spectrum below 300 kHz, making it ideal for specification tests in accordance with various standards such as USB-C.

The R&S ZNBT allows users to perform signal integrity tests in order to check crosstalk or length offset between lines or to detect faults in cables. Depending on the system to be measured, the R&S ZNBT40 is the right choice for measurements in development, service, and especially in production where substantial time and cost savings can be achieved by making up to 24 measurements in parallel.

In addition to measuring S-parameters on multiport devices, the R&S ZNBT VNAs can perform phase measurements on up to 24 signals. Rohde & Schwarz ensures specified performance on all R&S ZNBT test ports. Users can count on long-term measurement stability thanks to the instrument’s excellent raw RF data.
