[USRP-users] Keep transmitted signal in USRP to overcome the limited host sample rate of E100/E110

Dear Marcus,

Thank you for your answer.

In my case, I want to sent the periodic signal. It means that I just want
to keep one set of signal in FPGA and send it out repeatedly.
As my calculation, it takes < 100 Kbits. That's why I think that it can be
stored in FPGA of E100/E110.

Best Regards,
Jack
