[USRP-users] Phase sync with different frequencies

2017-11-25 Thread Bakshi, Arjun via USRP-users
Hi all, I'd like to use the phase resync freature on the SBX to get reliable phase alignment in the following setup: link_freq1 = USRP-A TX @ Freq1 ---> USRP-B RX @ Freq1 link_freq2 = USRP-B TX @ Freq2 ---> USRP-A RX @ Freq2 Where link_freq1 should always have phase X, and link_freq2 should a

Hi Arjun, You mention that you have both units connected to ‘external PPS source, and have a MIMO cable between them’. Not sure where the Vref is coming from but I presume over the MIMO cable? I wonder how you are setting the clock and time source but I had an issue wi

Hi John, Thanks for the reply. In my setup I make one of the USRPs use the time source and clock source as the MIMO cable, while both get an external PPS signal. Thinking about it now, it may have been better to just have everything from the external octo clock. My goal is to get the same ch
