“…Recently, optimized stirrers have been designed to improve the stirring performance [12]. Meanwhile, the source-stir technique has been applied to improve testing efficiency [13][14][15][16][17][18][19][20][21]. The multi-probe system, one of the stir techniques, is generally used in the RC [18][19][20][21].…”

The multi-probe system, one of the stir techniques, is generally used in the RC [18][19][20][21]. By placing several receiving antennas (source-stirring) on the wall instead of mechanical stirring, both the calibration and other measurements can be performed quickly.…”

To increase the speed of the measurement, a time-efficient multi-probe system in a reverberation chamber (RC) is validated. The system consists of 4 printed circuit board (PCB) switches integrating with 128 probe antennas. By using solid-state switches, all antennas can be switched over in sequence in less than 1 second. Typical characteristics of the RC and the total radiated power (TRP) of the device under test (DUT) are performed to verify the validity of this configuration. Compared with the RC using mechanical stirrers, this system shows its superiority in terms of testing efficiency.
