The Rohde & Schwarz ZN-Z30 is an inline calibration unit controller that automates periodic recalibration for vector network analyzers in production and metrology environments. It manages up to 48 inline calibration modules across two independent CAN bus lines, each supporting 24 units, enabling scalable multiport test configurations with minimal operator intervention. Remote operation via LAN from a VNA or external control PC eliminates manual calibration steps and reduces errors in high-accuracy measurement setups.
