The phase of the TX signal, as seen at the RX will be some function of
the propagation delay between the two, and the initial phase at the TX.
That's basic concep
Should the TX be the signal before it been received and after it been
transmitted?

Thank you.
Well, given that the only "view" you have of TX is after it has been
received, and before it has been transmitt
Thank you. I have read this,
it only shows the phase difference between two RX, how about the phase
difference between TX and RX?
Thank you.

Hi,
I have a USRP x310 and 2 UBX daughterboard. I'd like to send a signal
using RFA TX/RX port, and receive the signal from RFA RX2 and RFB RX2 port.
I am interested to get the phase difference between the RFA TX/RX and RFA
RX2, RFA TX/RX and RFB RX2, how to do that? Is any grc block that I
