Disclosed are a system and a method for a high-speed performance measurement. The system includes: a fixing part; a positioner for controlling the rotation of the equipment by controlling the fixing part; a measurement probe; a curved reflective plate for reflecting, in the direction of the measurement probe, an electromagnetic wave radiated by the equipment and transforming the spherical wave of the measurement probe into a plane wave at the position where the equipment is provided; an arc structure including an arc arranged to be adjacent to the fixing part; a probe set including near-filed probes arranged to be spaced predetermined intervals apart from each other on the inner side of the arc; and a control unit, which receives, through a signal analyzer, signal data corresponding to an input signal from some of near-filed probes and the measurement probe.

System for measuring performance of equipment under test, and method therefor

Disclosed is a radio wave device test system, comprising a fixed part configured to fix a radio wave device; a positioner system configured to control a rotation of the radio wave device by controlling the fixed part; an arch structure whose central point is located at a position where the radio wave device is located; a plurality of probes disposed to be spaced apart from one another at fixed intervals in the arch structure, and configured to receive a radio frequency (RF) signal from the raid wave device; and a plurality of receiving modules located at the plurality of probes, respectively, and configured to transform the RF signal into in-phase/quadrature (I/Q) data by carrying out digital transformation for the RF signal and to detect information on amplitude and a phase from the I/Q data.
