Rohde & Schwarz has expanded the frequency range of the R&S ZNBT, their multiport vector network analyzer that operates up to 20 GHz. The R&S ZNBT20, has 16 integrated test ports, with fast sweep times and excellent RF performance. It is a true multiport vector network analyzer and can drive all ports in parallel without the need for internal switching. Parallel measurements increase the throughput tremendously, which is particularly important for production applications.The high number of ports is relevant for the production of both active and passive multiport components such as frontend modules for multiband mobile phones or high-speed data cables. In addition, signal integrity tests can be performed for high-speed transmission standards, especially when combined with the R&S ZNBT-K20 option for extended time domain analysis, which allows eye diagrams, rise time and skew to be displayed on the R&S ZNBT.This new R&S ZNBT20 multiport vector network analyzer is now available from Rohde & Schwarz.
