Hi, I don't want my sampling rate to be 25 kHz. My sampling rate is already 195312 Hz which is I think the minimum sampling rate for X310. What I want is to filter out the frequencies which are at least 25 kHz away from my center frequency. For example I don't want to see a transmission which is

Hello Ali, To extend what Marcus has said, here is a link to the UHD manual page about sample rates. http://files.ettus.com/manual/page_general.html#general_sampleratenotes Regards, Derek On Mon, May 14, 2018 at 8:54 AM, Müller, Marcus (CEL) wrote: > Hi Ali, > > just like the

Re: [Discuss-gnuradio] USRP DDC and GNURadio Bandwidth Problem

Hi Ali, just like the console will tell you, 25 kS/s is simply impossible with an X310; instead, the minimum possible rate was used. You should probably just configure your X310 to get you e.g. 500 kS/s, and then resample in digital domain. If you're hesitant to design your own decimating

[Discuss-gnuradio] USRP DDC and GNURadio Bandwidth Problem

Hi to all, I am using GNURadio to control an X310. I want to get IQ samples for only 25 kHz bandwidth. When I wrote 25 kHz to the bandwidth line in UHD-Source block in GNURadio, I still see the signals at 50 kHz or 75 kHz away from the center. My sampling rate is 195312 Hz. When checked in
