The Rohde & Schwarz ZVB20 is a 2-port vector network analyzer operating from 10 MHz to 20 GHz, delivering dynamic range exceeding 115 dB and measurement speeds of 125 µs per frequency point. Built for RF component characterization, system integration testing, and production validation, the instrument combines a broadband signal source, precision receiver, and integrated 4-channel power meter in a single platform. Its configurable IF bandwidth (1 Hz to 10 MHz) and noise floor below -125 dBm enable detection of weak signals across demanding measurement scenarios.
