In the UHD tree you find a OOT in tools/gr-usrptest. If compiled + installed it will provide a tool called usrp_phasealignment.py. Using that you can "stress test" phase alignment with retunes and plot/prints the results. For the SBX you should get phase alignment across retunes/power cycling using that and a common 10 MHz Ref & 1PPS signal. Under the hood it uses a reconfigurable GNU Radio flowgraph, so it also should show if this works through GR API.
