Re: [USRP-users] 2011 Matt's Talk Materials

I am pretty sure those blocks all made it into GR core. Check the examples sections. On Mon, Oct 16, 2017 at 5:25 PM Sumit Kumar via USRP-users < usrp-users@lists.ettus.com> wrote: > Thanks Robin, I found the slides. However the talk which he gave in GRCon > 2011 was approx 3:30 hr long. > >

Re: [USRP-users] Removing DC offset on USRP B200

How would I then include negative numbers on the Verilog side to kill the offset? I'm a bit more comfortable with fpga design than with SDR, so for testing purposes I'd prefer to do it that way. ___ USRP-users mailing list USRP-users@lists.ettus.com

Re: [USRP-users] [RFNoC] Listen Before Talking (LBT)

Hi Felipe, 1) As with any custom RFNoC block, yes it would connect to the crossbar. 2) Yes, your understanding is correct. 3) You would have to define what "high latency" is. The block would certainly add latency to the path. I would expect it to be on the order of 1 packet due to packet

Thanks Robin, I found the slides. However the talk which he gave in GRCon 2011 was approx 3:30 hr long. Anyways do you also have the grc files used in the slides ! Thanks much Sumit On Mon, Oct 16, 2017 at 11:21 PM, Robin Coxe wrote: > Matt gave this talk again at GR Con

[USRP-users] 2011 Matt's Talk Materials

Hi, I was wondering if anyone has the materials for the famous talk by Matt Ettus in 2011 GRCon. *"Why Doesn't My Signal Look Like the Textbook?"* I remember it was hosted on Tom's webpage. The link is still there, however the files are missing. http://www.trondeau.com/grc2011-abstracts/ Go

Re: [USRP-users] Removing DC offset on USRP B200

Never use a throttle in a flow that includes actual hardware. You're probably connecting via USB-2.0, which wont' support two channels at 5Msps. The tuned center frequency has nothing to do with the sample rate. The sample rate determines the bandwidth centered around your center frequency

Re: [USRP-users] Removing DC offset on USRP B200

So as far as using Verilog goes, how would I remove the offset (as described in the original post)? I don't think I can use gnuradio because the sample rate maxes out at around 5 Msps (if I try to push past this, I get "The total sum of rates exceeds the maximum capacity of the connection), so

Re: [USRP-users] Removing DC offset on USRP B200

A quick note from the other Marcus. The UHD library is NOT a DSP library. If you need to "do things to my signal", you'll need to do that outside of UHD itself, which is really just a driver API for the hardware. This is the domain of software systems like Gnu Radio, or if you're doing this

Re: [USRP-users] rfnoc blocks with multiple inputs/outputs

Hi Dario, Interesting. I would expect 2 UBX-160 with 2 radio blocks into the 2 input ports to work. My best guess is that there is some issue with either the detected upstream nodes or the propagation of the stream command. It would be interesting to debug the

Re: [USRP-users] Removing DC offset on USRP B200

Hi Marcus, How do i produce a sum of multiple tones using the uhd libraries? tx_waveforms.cpp lets me set a center frequency with uhd::tune_request_t tune_request(LO_freq), but what I want is to see an output A1*sin(f1*t + phi1) + A2 * sin(f2*t + phi2) + ... Along similar lines, how do I change

[USRP-users] Ettus B210 full design simulation

Hi, I'm currently trying to find out a way to simulate the entire b210 architecture. I've find a "run_sim" command located in the directory : prefix/rfnoc/src/uhd-fpga/usrp3/top/b200/sim/b2x0/sim_b2x0_1 This command tried to run ISim but all the links looks broken. I've tried to figure out
