Hi Marcus,

Thanks for the information. Could you please also tell what is the accuracy with which the phases are aligned between USRP channels, when we use 10 MHz reference to align, in pico-seconds or nano-seconds?

Hi Marcus,
Do I need to use 1 PPS also along with 10 MHz reference? And are there any software commands to be used along with these hardware configuration for synchronizing multiple USRPs without octoclock? If so what are those commands?

You would do well to spend some time with this app-note:


Indeed, there are many app-notes that might be relevant for you.
