Hi Martin!

No, actually they are around 50 cm apart from each other and connected to two different PCs.
Frequency is set to 2.4GHz. But I didn't sync the clocks.
I am at the beginning of my research with USRP2 and I didn't expect I would have need to sync the clocks for such a preliminary experiment with sinusoidal signals.
Can you please point me to some reference on how and why we do it? In the meanwhile I'll continue to search in the archive.

Thank you very much.
