The Rohde & Schwarz ZNB43 is a benchtop vector network analyzer delivering 2- or 4-port measurement capability across 100 kHz to 43.5 GHz. Built for RF component characterization in development, production, and service environments, it combines exceptional dynamic range—up to 128 dB standard, extendable to 150 dB—with measurement speeds below 2.5 seconds per trace. Port connectors accept 2.4 mm and 2.92 mm male connectors at 50 Ohms impedance.
