Re: [Discuss-gnuradio] UHD clock rate in the usrp e310 - release 4

Gabriel, I didn't realize you were also tx'ing. You won't be able to go to an interpolation of 1024 on the Tx side. M On 04/16/2016 09:37 AM, Gabriel Pechiarovich wrote: > Hi I just tried your suggestion and it was ok for the RX side, but in > the Tx side the decimation wont go up to 1024, it

Re: [Discuss-gnuradio] UHD clock rate in the usrp e310 - release 4

Hi I just tried your suggestion and it was ok for the RX side, but in the Tx side the decimation wont go up to 1024, it only decimates up to 512, -- Asking for clock rate 16.384 MHz -- Actually got clock rate 16.384 MHz -- Performing timer loopback test... pass -- Performing timer loopback

Re: [Discuss-gnuradio] UHD clock rate in the usrp e310 - release 4

On the release 4 image, you can't do that. But you can set the clock to 16 MHz and use a decimation of 1000. Or you can use a clock rate of 16384e3 and a decimation of 1024, for a better decimation filter response. Cheers, Martin On 04/06/2016 06:11 PM, Gabriel Pechiarovich wrote: > Hi, thanks

Re: [Discuss-gnuradio] UHD clock rate in the usrp e310 - release 4

Hi, thanks for your answeri wasn't able to answer earlier. I was aiming to a 8MHz clock rate in order to use the DDC and get a 16000 sample rate. So i think i was misunderstood. Thank you very much Gabriel 2016-03-31 13:25 GMT-05:00 Martin Braun : > On the release 4

Re: [Discuss-gnuradio] UHD clock rate in the usrp e310 - release 4

On the release 4 image, you can't set the clock speed under 10 MHz. However, you can use a DDC (which is built in and automatically used). Simply set the clock rate to 32 MHz (or 16 MHz if this is MIMO) and the sample rate to 8 MHz. Cheers, Martin On 03/30/2016 05:02 PM, Gabriel Pechiarovich

[Discuss-gnuradio] UHD clock rate in the usrp e310 - release 4

Hi all, I've developed a flowgraph wich includes a qpsk modulator and and audio encoder, I used to run it in the E310 using the first release ( http://files.ettus.com/e3xx_images/e3xx-release-001/) and now trying to use the release 4. The problem is: in the UHD sink and source the clock rate was
