Rohde and Schwarz ZV ZVC/ZVM mainframe

The Rohde & Schwarz ZV family comprises vector network analyzers engineered for precise electrical network characterization across DC to millimeter-wave frequencies. These instruments deliver S-parameter, impedance, admittance, stability, noise figure, and pulse profile measurements with exceptional dynamic range and measurement speed. The ZV series spans five distinct product lines

ZVA, ZVB, ZVT, ZVL, and ZVH - addressing applications in aerospace and defense, component validation, and research environments.

Technical Specifications

Frequency Coverage: 9 kHz to 110 GHz (model-dependent); extended capability beyond 110 GHz with millimeter-wave converters. The R&S®ZVA110 operates 10 MHz to 110 GHz; R&S®ZVL6 covers 9 kHz to 6 GHz. Port Configuration: R&S®ZVA series provides 2 to 4 ports with 4-port operation to 67 GHz. R&S®ZVT series offers up to 20 test ports in a single instrument (R&S®ZVT20). Measurement Speed: Sub–3.5 µs per CW test point (ZVA series). Frequency sweep across 200 points completes in less than 5 ms. With the R&S®ZVA-K17 option and 5 MHz IF bandwidth, sampling time reduces to approximately 430 ns per point. Dynamic Range: Greater than 140 dB (ZVA series); up to 150 dB achievable at 1 Hz IF bandwidth for high-blocking direct-mode measurements. IF Bandwidth Options: 1 Hz, 10 Hz, 500 kHz, 1 MHz, 5 MHz, 30 MHz. Maximum 30 MHz IF bandwidth available for pulsed measurements. Output Power: Typically greater than 15 dBm at test ports; adjustable to less than –100 dBm with optional attenuators.
