Rohde & Schwarz ZNBT vector network analyser

The Rohde & Schwarz ZNBT vector network analyser covers the frequency range from 9 kHz to 8.5 GHz, with the base model equipped with four test ports. Depending on application requirements, it can be enhanced to include 24 ports. The ZNBT is primarily for use in the development and production of active and passive multiport components such as front-end modules for multiband mobile phones.

When fitted with its maximum number of test ports, the ZNBT is capable of determining all 576 S-parameters of a 24-port DUT. It needs no switching and therefore carries out multiport measurements faster than switch matrix-based multiport systems. Alternatively, the ZNBT can also measure multiple DUTs in parallel.

The unit also does away with the loss introduced by matrix switches, making it possible to deliver measurements with the instrument’s full dynamic range of 130 dB, a high output power level of 13 dBm and low trace noise. And it does not have a display - a space-saving feature - but can be controlled via an external monitor, mouse and keyboard or via an external touch screen.
