Hello I want to down convert a DCS 75MHz band to 20MHz or less, is it possible to do so, without changing the FPGA code. I am using NI USRP 2954R BR Snehasish

I know that RFNoC had issues with this type of configuration, but I think recently those have been resolved. Otherwise, you can do it on the software side--I'm guessing your bandwidths aren't large.

Hello Marcus Is there any article on how to do this? BR Snehasish ________________________________ From: USRP-users <usrp-users-bounces@lists.ettus.com> on behalf of Marcus D.
