your DSP logics to the FPGA of the USRPs, if you have licences for the needed
software (and if you are okay with HDL).

Hi all,
Theoretically, in frequency domain, the spectrum for SQUARE wave should be a
SINC and for the spectrum of RAMP wave should be decreasing with every odd
harmonics. A question that I want to ask is, will I get to see these frequency
spectrum in the Spectrum Analyzer after being
Hi all,
I am getting underruns and overruns when trying to run the UHD programs, both
GNU radio and C++. The maximum my computer can handle is 4MHz sampling rate
before seeing "U".
I've searched online and most people say, change a new computer into quad core
etc.
Are there any other ways
Hi all,
Just a quick question, everything done using the UHD C++ and GNU Radio
Companion, is it done in the FPGA or computer itself? I am using USRP B210 and
what is the FPGA used for, as I know Gnu Radio is a software-defined-radio
framework, and all the blocks execute on the PC host.
Thank
Hi all,
I have tried the tx_waveforms example and measured it using a spectrum analyser
(SA). However, no matter what input wave-type I chose, I will get the same
output seen in the SA. For example, when I chose SINE and a center frequency of
100MHz, I observed spectrums at 100, 300, 500 ,700
.
My apologies if I've missed this in another email, but what is your goal with
these changes?
Regards,
Derek

YMMV, remember this is a suggestion, custom changes to the FPGA don’t have any

Hi everyone!
For the FPGA source code written for b210, I noticed that the input to the
GPIF_D that is 32 bits, and then in went through some FIFOs up converting to 64
bits and then down to 12 bits output (tx_codec_d).
May I know what is the purpose of up converting and then down convert

As the title mentioned, what is the difference between master_clock_rate and

Thank you in advance!

Hi everyone,
I have tried to program the Spartan 6 FPGA using Xilinx 14.7 to send out a
signal and to control the AD9361. However, I couldn't get an output out from
the transmitter. Can I just solely on FPGA or must I use the API for the USRP
B210? What are the steps and procedures I have to
