Rohde & Schwarz ZNB4 Vector Network Analyzer

Overview

The Rohde & Schwarz ZNB is a vector network analyzer designed for applications in mobile radio, electronic goods, aerospace and defense sectors, as well as high-speed printed circuit board design. It is ideal for developing, producing and servicing RF components such as amplifiers, mixers, filters, connectors and cables.

The ZNB network analyzers feature a wide dynamic range of up to 140 dB (at 10 Hz IF bandwidth), low trace noise of less than 0.004 dB RMS (at 10 kHz IF bandwidth) and high output power of up to +13 dBm, adjustable electronically in a range of more than 95 dB. The analyzer combines high measurement accuracy with exceptional speed—better than 5 µs per point and excellent long-term stability for reliable measurements over several days without recalibration.
