The transmission line can act as a phase shifter depending upon how
long it is and how the GPS signal is being split.

Hi Matt
Even if you lock the USRP2 to an external reference, there will still be
drift relative to other things not connected to the same reference.
Can you give me an example? The PLL on the daughter board is also
connected with the reference cloc

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
connec

I tried with GPS signals and a sinusoid from the function generator as

picture of the phase error
