Re: USRP X300 Synchronization

Thanks for your response, Marcus!
I have observed a constellation rotation for OFDM subcarriers when I use the PC clock for synchronization. However, by using the channel model, I am able to see the QPSK constellation. 

Thanks!

No, it's several orders of magnitude worse and generally insufficient for anything where you need synchronization.

Hello Dears,

I would like to inquire about the synchronization of two USRPs X300, one acting as a transmitter (Tx) and the other as a receiver (Rx). If both USRPs are connected to the same laptop, I'm wondering if the accuracy provided by PC clock synchronization is similar (or close) to that achieved through GPSDO synchronization?
