I am interested to use Ettus B210 for DOA purposes.
According to, B210 is using AD9361 2X2 MIMO chipset.
According to AD9361 datasheet, both RX channels are being driven by the same LO.
However, according to, there is a phase difference between the two USRP-B210 channels.
According to, the RX channels are aligned in phase.
Would be glad to have a formal answer to the following 2 questions:
1. Is there a phase difference between the two USRP-B210 RX channels?
2. If there is a difference - what causes it?
Thanks in Advance.
