64-probe spherical near-field test system

This system uses the SG test system of SATIMO, which has high reliability and fast test speed.Support 400MHz to 6GHz test frequency band, the tested antenna only needs to rotate 180° horizontally to perform complete 3D measurement.
 
It supports a maximum antenna size of 2.5 meters and a maximum weight of 50 kg, which can meet the electrical performance indicators of small base station antennas, indoor distributed antennas, terminal antennas and other products.
