The Rohde & Schwarz ZNB20 is a high-performance vector network analyzer for precise RF component and network characterization. Operating from 100 kHz to 20 GHz, it delivers measurement speeds better than 5 μs per point with dynamic range up to 140 dB at 10 Hz IF bandwidth. The instrument supports 2-port or 4-port configurations with 50 Ω impedance and ruggedized 3.5 mm male connectors, making it suitable for production and development testing of amplifiers, filters, mixers, connectors, and cables across communications, aerospace, and consumer electronics sectors.
