Rohde & Schwarz ZVB20 10MHz – 20GHz Vector Network Analyzer

The Rohde & Schwarz ZVB20 is a four-port vector network analyzer operating from 10 MHz to 20 GHz, engineered for R&D, production, and quality assurance measurement of passive and active components. Its dual-generator architecture enables simultaneous signal output to two test ports, delivering parallel measurements and up to 4× throughput improvement over single-generator instruments - critical for multiport and balanced device characterization.
