Can you give me an example? The PLL on the daughter board is also
connected with the reference clock. I hope to know which part is not
connected to the reference clock.
The error has the same trend for all satellites. So I think the error
is not caused by the clock difference between the local clock and the
GPS clock.
Is there any method that I can decrease the phase drift in the USRP2 output?
