Yes, Marcus, the other USRP (the one with the GPSDO) passes the test_pps_input 
with source type gpsdo or mimo or external!

        Kind Regards,

                   John

  Thanks Marcus,
                           Here is the output of test_pps_input for the mate 
N200 connected through MIMO cable:

  See the application notes for your device.


Hmmm, this is puzzling for sure.

I've never used the MIMO cable, so I don't have much experience.

If the other USRP is running properly, it should be producing 1PPS.
