Rohde & Schwarz ZVA40 10MHz – 40GHz Vector Scalar S-ParaMeter Network Analyzer

The Rohde & Schwarz ZVA40 is a vector network analyzer operating from 10 MHz to 40 GHz, engineered for precise S-parameter characterization across RF and microwave components. Available in 2- and 4-port configurations with 2.4 mm or 2.92 mm connectors, the ZVA40 delivers dynamic range exceeding 140 dB across most of its frequency span, with optional measurement inputs reaching 150 dB from 100 MHz to 20 GHz. Measurement speed reaches sub-3.5 microsecond acquisition per test point in CW mode, with full 200-point frequency sweeps completing in less than 5 milliseconds.
