[Discuss-gnuradio]Reprogramming the fpga

Hi I add some logic at usrp_std.v and make .sof file with Quartus II but I don't know that how program to fpga. so I just wanted to know how do you go about Programming/reprogramming the FPGA in the USRP board (with byteblaster or anyting) at windows Thanks in Advance LEMONed -

[Discuss-gnuradio] Maximal signal bandwith for the usrp

Dear all, According the USRP v4 description: http://www.ettus.com/downloads/usrp_v4.pdf the usrp is able to process signals up to 16MHz. As the USB port is limited to 60MB/s, and if the samples are coded on 32 bits (16 for Q and 16 for I), th

[Discuss-gnuradio] Processing of OFDM signals

Dear all, As anyone been able to process OFDM signals with the USRP? In particular, I have seen that many works have been started to develop a HDTV decoder with the USRP. Have you been able to decode the OFDM symbols (and decode the HDTV signals) ? Thanks, Best regards, Pierre

JALLON Pierre 201932 schrieb: As the USB port is limited to 60MB/s That is net bandwith. You have to subtract the overhead. Moreover you have to find chipsets that really support this rate. Currently 32MB/s is a achievable value for the USRP. Patrick -- Engineers motto: cheap, good, fast:

[Discuss-gnuradio] How can I set the frequency of VCO?

Hi, I have written a code to set the frequency of VCO (ADF4360-0): bool flag = true; bool usrp_standard_rx::set_freq(double frequenza) { vector a; frequenza += -4e6; a = compute_regs(frequenza); if(a.at(0)==0) return false; write_all(a.at(0),a.at(1),a.at(2)); return true; }

[Discuss-gnuradio] Help:How to print the payload in benchmark_ofdm_tx.py

Hello, I am trying to print the payload in the send_pkt function defined in ofdm.py(/gnuradio-core/src/python/gnuradio/blks2impl). I have used the following lines of code in send_pkt function. f = open("txdata.txt","a") s=string(payload) f.write(s) f.close() However no file is created. I want to

Re: [Discuss-gnuradio] Maximal signal bandwith for the usrp

Hi, USRP can transfer data at maximum of 32MB/s using its USB2. When the data are 16 bit wide (16bit I and 16 bit Q) then maximum complex transfered data will be 8 Msps which gives idealy maximum 8 MHz bandwidth. However, if we use 8 bit data wide ( 8bit I, and 8bit Q), then maximum transfer will

Re: [Discuss-gnuradio] looking at a wider spectrum

Hi, Use usrp_fft.py with decimation rate of 8. In this case, you can see 8MHz of spectrum. Also, you can use 8 bit data transfer with decimation rate of 4 to look at 16 MHz wide spectrum. Firas meggahertz wrote: > > I am new to the GNU Radio and am running the usrp_wfm_rcv.py but it only > sh
