AWR1843BOOST: 3 antenna transmission beamforming

Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843

Hello,

May I ask how to achieve the same chirp while transmitting from three antennas simultaneously?
I am currently opening all three transmission channels, and when configuring chirp, I will configure the transmission channels to 1, 2, and 3, so that all three antennas can transmit simultaneously?
I saw in the data manual of AWR1843 that only two channels can be transmitted simultaneously. However, when conducting my own experiments, I can set the transmission channel to three transmission channels during chirp configuration. May I ask how many channels should be transmitted simultaneously?

I saw in a document that three launch channels can launch simultaneously.

Regards,

Gary
