hi,
Im using a USRP2 as 2 Rx(Antenne J1 and J2).and using a USRPN210 as Tx.
when I started flow graph, i saw 'DDDDDDD' keeping showing up.and when I
changed USRP2 as 2 Tx and USRPN210 as Rx, i saw 'SSSSSS'.

I also tried turn the realtime scheduling on.But it killed the flow
graph immediatly after i started my flow graph.

above is the setting im using:
samp_rate=2M
carrier_freq=2.49G

problem may come from the USRP2.thats also what i wonder after checking
http://www.ettus.com/content/files/kb/application_...

it says USRP2 can be used as 2 Rx at sametime or 1 Rx and 1Tx.
so i even tried use USRP2 as 1Tx sending pure cos signal but in the Tx
side i saw nothing showing up.


is there something i made wrong or it just the time i sould upgrade my
computer?(which the most googled solution of the problem)
