Hello Koyel: I used a generic Intel i5 PC, with a Mellanox 10Gbps NIC. I do not remember the exact model numbers, but I am pretty sure that the cpu was a relatively older generation on (DDR3-era). I just created a tmpfs and used uhd_rx_cfile.py (a sample application included in gr-uhd) to

Hi Marcus, Good that you replied my email. Since you work on Radio Astronomy as I heard from Neel, I want to ask you something. By using USRP I saw that without any special configuration the phases of any two channels of USRP 2955 are phase coherent and the phase difference value is constant

Hi Marcus, Many thanks for your reply. I saw in simulation adding a DC offset in the phase difference between two channels has no impact in the Delay- Rate spectrum. It is giving the same spectrum without this offset. The delays (td1-td2) are same in the delay spectrum with and without offset.
