Multi-probe Systems
SG Evo
400.00 MHz – 30000.00 MHz

The SG Evo is a multi-probe system for spherical near-field measurement and OTA testing, particularly suited for large DUTs and high accuracy applications. It incorporates oversampling positioning within the arch, eliminating the need to tilt the device under test (DUT) when oversampling, and consequently avoiding gravitational deflections of the DUT and azimuth positioner, even when testing heavy DUTs. The SG Evo can be configured with multiple parallel receivers, to reduce measurement time especially when testing multiple frequencies or devices with many potential antenna beam states.
