The Rohde & Schwarz ZN-Z150 is a 2-port calibration unit that enables automatic error correction and systematic compensation for network analyzer measurements across 5 kHz to 6 GHz. Powered and controlled via USB connection from compatible Rohde & Schwarz analyzers, this unit eliminates manual calibration kit handling and integrates with ZNA, ZNL, ZNLE, ZVA/T, ZNB/T, and ZND series instruments. The ZN-Z150 features electronically switched internal standards that do not wear out, delivering repeatable calibration performance across the entire frequency range.
