Mr. Josh Blum, Mr. Matt Ettus, Friends, I think that you are following discussion on the mailing list that is "phase-lock problem across USRP-2 boxes". Mr. Juha Vierinen kindly helped us with the information that
-- USRP-2 FPGA with GNU Radio original does not support "phase-lock across USRP-2 boxes". -- USRP-2 FPGA with UHD supports that. -- The "phase-lock across USRP-2 boxes" is the "NCO phase reset at PPS input". Are these true? We are developing a radar receiver, and already have a working program with GNU Radio original FPGA. For us, easiest way is to use a revised FPGA with "NCO reset at PPS" over GNU Radio. Is there such version of the FPGA image? The other way may be for us to switch to the UHD. What do you suggest? As our application is a radar receiver. Then in our program, we apply the TX pulse to PPS input, and reset the time counter at the TX pulses. Is this possible with UHD? This is one critical point for us to move to UHD. I hope your help. Thanks.
