[USRP-users] Question on max. baseband bandwidth: can we go above 120 MHz on the TX side?

Hi list,

We were discussing with some colleagues today whether to use a USRP (x300 specifically) to generate wideband noise with a basicTX for testing purpose. According to the data-sheet, the x300 can do 120 MHz of RF bandwidth from the host. But when I look into http://www.trondeau.com/storage/grcon14/presentations/Sep16_05_Ettus_Updates.pdf, I see 300+ MHz on slide 9. And if I look further in the spec, the DAC can go up to 800 MS/s.

Therefore my question: if we were to generate signals directly from the FPGA; would it be feasible to generate 400 MHz wide signals (I understand that the basicTX is limited to 250 MHz though)? Where would be the limitation?

Thanks for any comment
