Hi,
I have included this line in my python flowgraph:
|||sink.config_mimo(usrp2.MC_WE_LOCK_TO_SMA)
where sink is: ||sink ||=| |usrp2.sink_32fc()|
but I think USRP2 is not locked to the external reference clock since
when I turn this ref clock generator off, there is no change in the
spectrum of the output of USRP2. My understanding is that if USRP2 is
locked to the ref clock, when I turn the clock off I should see no
signal at the output of USRP2. can somebody please help me with this?
How do I get the USRP2 to lock to the ref clock?
I believe this is a reference clock, not an external clock. If so,
the USRP would continue to run on its internal clock, which has been
synced to the reference clock. When the ref clock is removed, the
internal clock would continue to operate, slowly drifting.
