Rohde & Schwarz ZNB26 Vector Network Analyzer (4-Port)

Overview

The Rohde & Schwarz ZNB26 is a 4-port vector network analyzer designed for comprehensive RF component testing up to 26.5 GHz with 2.92 mm connectors. With its ability to measure all four S-parameters simultaneously, the 4-port configuration is ideal for complex RF module characterization in development, production, and service applications. The analyzer combines high measurement accuracy with exceptional speed and excellent stability for reliable multi-port measurements.

The ZNB26 delivers outstanding RF performance with a typical dynamic range of 140 dB, trace noise below 0.004 dB RMS, and adjustable output power over a 95 dB range. Its fast synthesizer settling times and large IF bandwidths enable short measurement periods, making it well-suited for high-volume RF production environments.
