I TScan
TScan is a fast and ultra-accurate planar near-field scanner with the latest motor drive and encoder technologies. High acceleration of the linear motors for stepped and continuous mode operation optimizes the performance and cost of the scanner. Excellent manufacturing precision combined with direct readout high resolution linear encoders and careful alignment ensure unrivaled mechanical positioning accuracy and planarity. The positioning accuracy for all axes can then be further improved using MV-Cor™*.

Max. weight of DUT
DUT is stationary, therefore the maximum weight of the DUT is limited by the foundation, antenna mount including any DUT alignment features, and building infrastructure.
Typical dynamic range
80 dB, depending on the frequency and antenna gain
Available movements
X – travel: up to 50 m Z – travel: up to 3 m
Y – travel: up to 26 m Polarization: 360°
Note:
• To include cylindrical and spherical near-field measurement capabilities in
a planar facility, one can choose to install the DUT on an azimuth positioner (cylindrical) or a roll-over-azimuth positioner (cylindrical and spherical).
• Longer travel ranges are available based on special order.
