Hi All, I am giving up hope of sampling signals of full BW of two UBX-160 cards, and storing those streams in the PC. Based on my calculations (one of the previous posts) in order to be able to do that I would need to write to memory with the speed of 1.6GBps.
However, now I am interested in sampling short bursts of signals with the full bandwidth of USRP x310 (so 2(cards)x2(IQ)x200MSPs) and then storing them into PC memory for the period of 10 minutes. The idea would be to stream bursty signal when the signal is in the air. For this, I would probably need to have some sort of energy detector in the FPGA. The idea would be that energy detector signalizes when the signal is in the air and to trigger streaming samples towards PC. In this way, I would try to lower requirements on the speed of memory write in the PC. Does anyone have experience with doing the same? Previously, I was interested in the possibility to connect single USRP-X310 to two separate PCs over 10GBe interfaces (to split dual 10GBe connection to two PCs with NVMe SSDs). In that way, there would be a possibility to lower down requirements on memory writing speed to 0.8GBps. These memory writing speeds should be supported by modern NVMe SSDs. Probably this is not straightforward to achieve as I did not get too many replies on my previous post. More details about my previous posts are available here https://www.mail-archive.com/usrp-users@lists.ettus.com/msg05579.html. Cheers, Tarik
