Again, I am not sure what your objective is with regards to phase noise
performance, but, remember that within the loops BW you will get the phase
noise of the source. In this case the GPS. The phase noise spectral density
will be modified by the loop's roll-off and then outside of the loop it will
be that of the 10811A. - Mike

6) Finally add a GPS, which should give me the low phase noise of the 
10811A, with a decent holdover time from the PRS10 if there is no GPS
