Rohde & Schwarz ZNB26 Vector Network Analyzer (2-Port)

Overview

The Rohde & Schwarz ZNB26 is a 2-port vector network analyzer designed for high-frequency RF component characterization up to 26.5 GHz with 2.92 mm connectors. It combines high measurement accuracy with exceptional speed—better than 5 µs per point—and excellent temperature and long-term stability for multi-day measurements without recalibration. This model is ideal for development, production, and servicing of RF components in mobile radio, aerospace, and defense applications.

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. These characteristics enable precise characterization of amplifiers, mixers, filters, connectors, and cables across the microwave spectrum.
