The signal transmitting module 1 is used to transmit wireless signals, and the signal receiving module 2 cooperates with the signal transmitting module 1 to receive the wireless signals transmitted by the signal transmitting module 1. The signal receiving module 2 is mounted on the turntable module 3, which includes an azimuth turntable 31, a pitch turntable 33, and a polarization turntable 32. The azimuth turntable 31 is used to drive the signal receiving module 2. The azimuth rotation is performed by a pitch turntable 33, which drives the signal receiving module 2 to rotate in pitch, and a polarization turntable 32, which drives the signal receiving module 2 to rotate in polarization. The turntable drive module 4 is electrically connected to the turntable module 3 to drive the turntable module 3 to move. Specifically, the turntable drive module 4 includes an azimuth drive motor for driving the azimuth turntable 31 to rotate, a pitch drive motor for driving the pitch turntable 33 to rotate, and a polarization drive motor for driving the polarization turntable 32 to rotate. The bit error rate analyzer is electrically connected to the signal transmitting module 1, the signal receiving module 2, and the oscilloscope 5, respectively.

[0041] The bit error rate analyzer is used to analyze the bit error rate of data transmission between signal transmission module 1 and signal receiving module 2, and to monitor the signal transmission quality in real time; the oscilloscope 5 is used to monitor and analyze the waveform, eye diagram, etc. of the antenna transmission signal; in practical applications, the antenna unit under test is used as the antenna unit in signal transmission module 1 or signal receiving module 2 in the antenna bit error rate test system.

[0042] The physical connection relationship between the azimuth turntable 31, pitch turntable 33, and polarization turntable 32 in the turntable module 3 can be configured as needed. For example, the azimuth turntable 31, pitch turntable 33, and polarization turntable 32 can be connected in sequence, and the signal receiving module 2 can be installed on the polarization turntable 32; the azimuth turntable 31, polarization turntable 32, and pitch turntable 33 can be connected in sequence, and the signal receiving module 2 can be installed on the pitch turntable 33; the pitch turntable 33, azimuth turntable 31, and polarization turntable 32 can be connected in sequence.
