Do USRP SDRs sync sampling timing?

Hello.

I not sure if I should buy some usrp.

I want to experiment 4×4 MIMO.

first, I am experimenting SIMO with BladeRF. I set transmitting QPSK signal from Tx, and receiving signal with two BladeRF.

Result two receiving IQ data charts should be same because of single input. But not same, One is rotating.

I think BladeRF SDRs don't sync starting sampling timing. Do USRP SDRs sync? What kind of usrp?

Hello yusho.n 

Considering on the BladeRF device, which is NI tired party device. To be honest, I couldn't understand how you tried to synchronize devices.

To be shot, yes, you can synchronize your devices, there is a link where you can find appropriate information about synchronization and MIMO Capability with USRP Devices. Try to go through that article to understand the concept of synchronization, also, find the USRP capable devices written in this article.
