Re: [Discuss-gnuradio] Higher sample rate

[scott tiger]

Thank you very much for your reply.

There isn't any switch or router between USRP and computer. They are connected by Ethernet cable.

the folow-graf is not complex at all, but the signal is transmitted from the saved file and the received signal is recorded to hard disk. I tested to do that on different computers with CPU (dual core, i3, i5, i7) but I didn't mentioned any big difference.

Dear all,
Can you please tell me, what is the max sample rate that can be used in gnu-radio for SISO transmission with USRP 2 or N200 series? "of course practically"
theoretically it is written up to 50M, but the max that I achieved is 12M.
any ideas about the host computer characteristic to achieve higher sample rate?

Thank you very much for your reply

It depends very much on what you're trying to do, how complex your flow-graph is, etc.

In general, faster CPU cores, more of them.   The fastest memory you can use with said CPUs.  If you're recording to disk, or transmitting from saved signals, a fast, probably-RAID disk subsystem.
