Re: [USRP-users] 10 MHz Reference Initial Phase in the X310

I guess I just need to think more about the problem. With your explanation I still don't understand why the 1 PPS would be detected differently in the two situations, and I still don't understand why the phase of the 10 MHz reference with respect to the 1 PPS should matter. I can understand some va

Hello, I am attempting to release a transmission from an X310 every second. To accomplish this, I must measure, and calibrate the delay in the RF front end of the radio for my chosen sample rate. I'd like the transmission to be released within 1 clock cycle of the rising edge of the PPS. I am fee
