The R&S ZNBT8 is claimed to be the first multiport vector network analyser offering up to 24 integrated test ports. The instrument can simultaneously test multiple DUTs or measure one DUT with up to 24 ports.

The device offers short measurement times even in scenarios with a large number of ports. Other highlights include a wide dynamic range; high output power levels; and inputs featuring high power handling. The instrument operates in a frequency range from 9 kHz to 8.5 GHz. These features make the product suitable for applications in the mobile radio, wireless communications and electronic goods industries.

The instrument is primarily used in the development and production of active and passive multiport components, such as GPS, WLAN, Bluetooth and front-end modules for multiband mobile phones. However, its performance even allows efficient analysis of base-station filters and associated demanding devices.

The product is said to offer superior performance over switch matrices. Its high integration density provides a compact solution for analysing components for up to 24 ports, occupying the same rack space as an R&S ZNB. The convenient user interface makes it easy to handle even complex multiport measurements.
