View all threadsStoring signals with full bandwidth of USRP x300/x310
Hi all,
USRP x300/x310 is able to stream 200MS/s (800MB/s), which is enormous
volume of information. Not many PC's are able to receive such flow of
data, let alone to store several dozen minutes of it.
Thus I want to ask you, USRP x300/x310 developers and users, what set of
hardware enable you to store the data flow from your USRPs?
In my case I need a system that can be powered with battery, possibly
small and mobile (quite conflicting requirements). However at the moment
proposition of any system that is able to sustain 200MS/s and store it
will be good.
Best Regars,
Piotr Krysik
Piotr,
The majority of users of X300/X310 are actually processing the data in real
time either in the host computer or in the FPGA. Storing samples at 200
MS/s is possible, but not easy. There are consumer-level SSDs which can do
sequential writes at about 500 MB/s:

With 2 or 3 of those in a RAID configuration you should be able to keep up
if you design your app right. That being said, you'll fill the drive
pretty quickly, so an array of cheaper spinning disks may make more sense.
Some people have had luck with 8 drive arrays.

Thank you Matt for the quick reply.
The requirement to store the data is quite common in radiolocation (i.e.
SAR imaging) as the radar data is often postprocessed with use of
different algorithms. Examples of equipment that can be attached to USRP
x300 in order to store/send large amounts of data with high bandwidth
might be very valuable for users performing radar measurements with use
of the USRPs.

Does anyone have experience using something like the OCZ RevoDrive 350 PCIe
x8 SSD rather than a RAID array?
