Tomi Teppo, Derek McKay-Bukowski, and I have been working on the 16-channel USRP N210 system that I put together before I left _. In anticipation of using this with a phased array antenna array in Kiruna, the setup needed to be modified in a way that all USRPs communicate via a switch, as the field site only has one fibre optic cable going into the building. A few days ago, we completed the setup and verified that we can do get 16 channels through a switch. This was not possible just a little while ago, so the firmware has definitely improved. Before all the channels were directly connected to the computer. Hurray!
This system will have many cool uses with eg., riometry, or HF radar imaging.
|16 channel USRP N210 setup.|
|8 USRPs going one switch, which has one 1 Gbit line going to the computer. I don't know what the upper switch is for though (maybe testing).|
|All the equipment. Everything is still a bit tangled.|
|Two computers. More computers can be added if we need more bandwidth or computational capacity.|
