Thanks for the clarification. We have both XCVR2450 TX boards (in the same TX USRP1 ) locked to 2.4GHz ( verified with a specturm analyzer ) . Now, the receiver XCVR2450 RX board (in the RX USRP1 ) should be able to lock to 2.4GHz as well , right ?
We're using default BPSK mod/demod for this 2 TX x 1 RX experiment. Both TX boards send BPSK symbols in the same time slot, and are tuned for 2.4GHz Is there a lock-detect pin on the RX side we can probe to verify that the RX board has locked to 2.4GHz ? -Nick On Fri, Jun 8, 2012 at 7:34 PM, Matt Ettus <m...@ettus.com> wrote: > > Each XCVR2450 is already locked to the motherboard crystal.
