HScan

HScan is a fast and ultra-accurate horizontal near-field planar scanner particularly suited for the antenna measurement of space-borne antennas, large reflectors and certain vehicle mountedantennas. HScan also enables the testing and calibration of multi beams of phased array antennas. Hscan integrates the latest motor drive and encoder technologies. Excellent manufacturing precision combined with direct readout high resolution linear encoders and alignment capabilities ensuresunrivalled mechanical positioning accuracy and planarity.
