Hello: I am trying to sync up the clocks on two USRP2 boards. How do I use the external reference clock "REF CLOCK" input on the USRP2 board? What does this input take? My understanding is that it takes a 10 MHz sine wave, 1 volt peak-to-peak.
And how do I enable this input? Do I need to set anything in my flowgraph?
Thanks.
Steve McMahon
