The Rohde & Schwarz ZV-Z58 is an eight-port automatic calibration unit engineered for precise system error correction in vector network analyzers. It provides electronically switched internal calibration standards with stored calibration data, enabling direct error-term computation without manual input. The unit connects via USB directly to compatible R&S network analyzers and operates across 300 kHz to 8 GHz, delivering the stable, well-defined reference required for accurate multi-port measurements.
