The Rohde & Schwarz ZN-Z154 is a multi-port calibration unit engineered for network analyzers operating from 100 kHz to 8.5 GHz. It delivers precise, simultaneous multi-port calibration by connecting all test cables once, then executing calibration with a single command. The unit automatically detects connected test cables and port assignments upon startup, eliminating manual configuration errors and significantly reducing calibration time. With base configuration supporting 6 ports and expandable to 12, 18, or 24 ports via optional hardware modules, the ZN-Z154 accommodates diverse measurement architectures.
