DUT
RRU + Massive MIMO antenna array
The test content
RRU uses different test signals to verify the beamforming effect. Antenna array pattern after measuring beam formation.
Test steps
1. Use DUT as the transmitting antenna and place it on the test turntable; 2. The standard horn antenna is used as the receiving antenna to connect the input end of the instrument in the test field; 3. Set a reference clock signal between the DUT and VNA to ensure device synchronization. 4. Use standard horn antenna to collect DUT amplitude information in real time.
