Hi Marcus and Derek, Thank you for the reply. The RFNoC and synchronization are very helpful. I have an additional question regarding to the timestaming in GNURadio. In the VITA and CHDR format of RFNoC, there are timestamp and stream ID, what could I do to keep the timestamp and stream ID via a

I found that UBX has a bit less of spurs. I assume it is because the whole daughterboard is covered by heatsink panel that plays a role of EMI shield while SBX is open. thanks, Dmitry From: Hojoon Yang via USRP-users Sent: 14 марта 2018 г. 9:23 To: usrp-users@lists.ettus.com Subject:

Hello Hojoon Yang, Both SBX and UBX will work fine (*Assuming X3x0 series only, no N2x0 or older boards). You can align the phase of the UBX and SBX boards by using the timed commands ( https://kb.ettus.com/Synchronization_and_MIMO_Capability_with_USRP_Devices ) , but you will have to

I have found that it starts happening with low sample rates around 2 Msps and then stops overflowing. It happens all the time with higher sample rates. I tried to rule out my code from this by having it run in a thread that just reads from the device and then discards the data afterwards.

[USRP-users] UBX vs SBX

Hi.I have two USRP X310s and wonder which board between SBX and UBX would be the suitable for me.I'm gonna buy four daughterboards to use it as 2x2 MIMO. One USRP X310 for Tx, the other USRP for Rx.My target frequency is from 1.8GHz to 2.8GHz. According to datasheet, Both UBX and SBX work on
