Dear All, I am trying to implement some frequency hopping schemes in the ISM band with USRP N210 with RFX 2400 board ( I also tried the same with the SBX 40MHz board). I hop to the next channel (channel seperation : 5MHz) after every 6ms (tuning time for RFX board is 250usec) so tuning is not an i

Hi All, I just came across this talk "Spread Spectrum Techniques in GNU Radio" in GNU Radio Conference ‘14. The presentation ( http://gnuradio.squarespace.com/storage/grcon14/presentations/Sep18_07_David_DSSSFHSS.pdf) tells about the Spread spectrum toolkit developed. I am trying to find the toolk

[Discuss-gnuradio] Frequency Hopping Transmission with USRP N210 : Query

2015-02-09 Thread vaibhav kulkarni
Hi All, I have a USRP N210 with RFX2400 2.3-2.9 Ghz RX/TX. I have recorded a trace at 2.41 GHz and stored it to a file filename.dat. I want to transmit the same trace at 2.415, 2.420, 2.425 so on till 2.440. So, I used the freq_hopping.py python utility under the python examples folder in gnuradi

[Discuss-gnuradio] High Precision ISM Band Spectrum Recording with USRP N210

2015-01-27 Thread vaibhav kulkarni
Hi All, I have a USRP N210 with RFX2400 2.3-2.9GHZ RX/TX. I want to view the ISM Spectrum band from 2.40GHz - 2.48Ghz. Record it with a very high precision. I have the following doubts : 1. Which port the antenna should be connected to get better accuracy ? TX/RX or RX. As said, I just want to r

[Discuss-gnuradio] Changing the IP of USRP2
