G-DualScan
I G-DualScan
G-DualScan represents a step forward in spherical near-field measurements. It measures antennas
with large dimensions and analyzes a very broad range of frequency bands from 200 MHz
to 18 GHz. It consists of a single-probe gantry arm and a multi-probe arch up to 12 meters (40
feet) in diameter.
