The Rohde & Schwarz ZN-Z32 Inline Calibration Unit Controller automates vector network analyzer (VNA) calibration across 10 MHz to 8.5 GHz, eliminating manual intervention in RF and microwave test environments. This CAN bus-controlled system manages multiple inline calibration modules simultaneously, delivering recalibration in seconds while maintaining consistent measurement uncertainty—critical for production automation, thermal vacuum (TVAC) chambers, and inaccessible test setups.
