– Compatibility & Integration
The ZN-Z153 integrates with Rohde & Schwarz ZVA/B/T and ZNB/C series network analyzers. Control and configuration rely entirely on the host network analyzer, allowing operators to execute full automatic calibration workflows without external software. The unit is optimized for economic, repeatable calibration across single and multiport test configurations.
