Rohde & Schwarz ZNB43 43.5GHz Vector Network Analyzer

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.
