Hi David,
you're right, the scheduler
Dear All,
I am using N210s with XCVR2450s. I have successfully performed 2x1
transmission, but not I am not transmitting the same stream over both
transmitters. One stream is constantly available, and is no problem. The second
stream only starts later on, and thus it is blocking the flow

Hi David,
Generally, this sounds like in principle, your application looks like

Hi David,
easiest way to achieve coherence on both USRP would be a MIMO cable,
or GPSDO's.
That being said, depending on your definition of sync, just setting
the time at both USRPs would little

Hi Marcus,
Thanks - I require sample level timing sync. Using the external sync to get
accurate LO frequencies is great, but not sufficient. Using a single UHD
block with 2 motherboards gives me sample-level sync.
That will only be true if
