choosing an RF daughterboard

[baharehbb]

Hi every one,

I have used USRP1 with two WBX daughterboards for a direction finding project. The problem was that as a simple experiment with two sinusoid signals generated from signal generator that have let say 60 degrees phase difference at the input of USRP, in the output whenever we re-tune or restart the device we received a different random phase offset in the phase difference of outputs. 
I mean for one experiment we had a phase difference and it remained constant to the end of that experiment but once we just turned the device off and start again we got a different phase offset between signals.


Now we want to buy another USRP, their representative told me that SBX dbs can solve the problem. I would be thenkful if I can have your opinion and help about what is the best choice.

Thanks,

Hi baharehbb,

The USRP1 is best stupported by Ettus Research as they will have more resources to answer your questions. If you would like to ask them your technical questions, I have linked their support page below:

I hope this is able to point you in the right direction.
