[Discuss-gnuradio] anyone have success with USRP2 @ 20MHz to the host cleanly?

2009-11-22 Thread George Nychis
Hi all, Has anyone here had any success with receiving 16-bit samples from the USRP2 @ 20MHz to the host without an onslaught of overruns? I did some searching on the list and some people suggested a RAID configuration, but this is my poor little laptop. Just wanted to get a general consensus.

Thanks for the suggestions! I am digging the ramdisk idea... unfortunately the laptop only has 1G of memory, but I can still get a hardy 10 second trace out of it :) I liked the compression idea, Dan. I wonder if we can get something that can keep up with the data rate. It seems like a challeng

If latency and RAM usage is not an issue, increase the ethernet packet_ring buffer (I'm normally using from 0.5 to 1 GB). I wrote a patch some while ago and I think it is now in gnuradio, but I'm not sure if it is in the python interface. This will probably help you closer to the long term average
