Hi Eric,
Is there any DC(low frequency)removing/coupling effect in the USRP that
arises due to syncronization?
Because, before I syncronize the boards i was able to transmit,for
instance at 4.96GHz and receive a narrow band carrier at the same
frequency,4.96GHz. Now, I am able to see the correct spectrum if and
only if i receive at a frequency offset greater than +/- 1KHz.
