Rohde and Schwarz ZV-Z51/3.5mm Automatic Calibration Unit, 2-port

The Rohde & Schwarz ZV-Z51/3.5mm is a 50 Ohm calibration kit designed for precise two-port network analyzer calibration. It delivers systematic error correction across RF and microwave measurements, enabling repeatable accuracy in professional laboratory and field environments. The kit includes four essential calibration standards: Short, Open, Matched Load, and Thru, each manufactured to exacting tolerances to minimize measurement uncertainty.

Technical Specifications

• Connector Type: 3.5mm (K)


• Impedance: 50 Ohm


• Calibration Method: Two-port calibration

Key Features The Short Circuit standard characterizes and corrects reflection errors at the reference plane. The Open Circuit termination models and compensates for open circuit conditions in the measurement path. The Matched Load presents nominal 50 Ohm impedance to measure and correct transmission and reflection errors due to impedance mismatch. The Thru component provides direct port-to-port connection, effectively simulating zero-length transmission line behavior and calibrating for transmission errors and direct coupling. All standards employ high-quality 3.5mm connectors engineered for durability and consistent electrical contact through repeated laboratory and field use.

Typical Applications The ZV-Z51 serves system integrators, laboratories, and enterprise procurement requiring accurate RF and microwave characterization. It is essential for S-parameter measurement, impedance analysis, and systematic error removal in network analyzer workflows.

Compatibility & Integration The ZV-Z51/3.5mm works with Rohde & Schwarz network analyzers equipped with 3.5mm connectors. It is generally compatible with other network analyzers featuring 3.5mm interfaces at 50 Ohm impedance. Users must verify compatibility with their specific network analyzer before deployment.
