Rohde & Schwarz ZV-Z21 18GHz 50 Ohm N Type Calibration Kit

The Rohde & Schwarz ZV-Z21 is a precision calibration kit for vector network analyzers, delivering the TOSM standards required for accurate RF and microwave measurements to 18 GHz. Built around 50 Ohm impedance and Type-N connectors, It has the mechanical stability and repeatability essential for high-accuracy error correction in demanding measurement environments.

Technical Specifications

Frequency Range: DC to 18 GHz
Impedance: 50 Ohm
Connector Type: Type-N (female)
Standards Included:

• Through (T)


• Open (O)


• Short (S)


• Match/Load (M) Connector Configuration: Male and female connectors available for both insertable and non-insertable calibration scenarios.

Key Features Each standard is individually characterized with S-parameter data, enabling data-based error correction models in networked analyzers for enhanced measurement accuracy. The kit ships with a torque wrench and counterholder to ensure proper tightening and mechanical contact repeatability. A USB stick containing calibration data is typically included. Mechanical design emphasizes stability and reproducibility - critical parameters for eliminating systematic errors in VNA calibration workflows. The balanced male/female connector set accommodates both direct-insertable calibration and setups requiring adapters or indirect connections.

Typical Applications Primary use spans R&D laboratory work in RF and microwave characterization. The kit supports high-accuracy calibration across component testing, amplifier characterization, filter measurements, and impedance analysis workflows where systematic error correction is non-negotiable.

Compatibility & Integration Designed for Rohde & Schwarz vector network analyzer platforms including the ZVA, ZVB, and ZVT series. The kit is compatible with uncertainty analysis workflows using the R&S ZNA-K50(P) option, enabling traceable measurement confidence statements. Part of the R&S ZV-Zxx calibration standard family, it integrates directly into existing R&S measurement ecosystems without adapter interfaces.
