The SG Evo is a multi-probe system for spherical near-field antenna measurement and OTA testing particularly suited for large or heavy Devices Under Test (DUT) and high accuracy applications. Its unique design enables unlimited sampling thanks to a precision positioning mechanism in the arch. This eliminates any tilting of the DUT, consequently avoiding gravitational deflections of the DUT and azimuth positioner. The SG Evo can also be configured with multiple parallel receivers to reduce measurement time, especially effective when testing several frequencies or devices with many potential antenna beam states.
