Hi All,

If we had an fpga image that allowed us to store samples on the USRP2 
that would be very benefitial, at least for me. Then one could test 
algorithms with 100MHz sample-rate. Yes, it would not be possible to 
use the channel continously. Receiving 1ms of samples would take 4ms to 
upload. However, using the time-stamp functionality one can synchronize 
nodes to transmit and receive at the same time and thereby enable 
testing e.g. interference rejection algorithms.
