Built using innovative hardware and software concepts, the vector network analyzers of the ZVB family set new standards: One generator can feed two test ports simultaneously. This makes parallel measurements possible and thus significantly increases performance despite the complexity of the measurement task at hand. In particular, multiport measurements such as performed on balanced SAW filters, duplex filters or antenna switching modules can, therefore, be completed very quickly. The ZVB combines excellent performance with low weight and compact design. Intelligent and user-friendly functions offer maximum ease of operation. They allow the large number of measured quantities involved in multiport and balanced measurements to be handled easily, and also offer a variety of ways to optimize production sequences – a smart solution that satisfies even the most challenging demands.
