[Discuss-gnuradio] GNU Radio, peak values, export into a file

Hey all! I started working with GNU Radio and HackRF One SDR for an university project but I'm completely complete new and I'm still a little bit lost. I'm using the HackRF One as a spectrum analyzer, specifically at 120.457 KHz. That signal source comes from an Avalanche Transceiver upconverted

Re: [Discuss-gnuradio] [GSoC18] Student projects announced!

Hello everyone, I really look forward to doing some awesome work with GNU Radio this summer. And yes, I'll be posting the weekly blogs about the status of the project in contrast to the specified deadline. I will also remain in frequent touch with the mentors throughout the program. Thank you,

[Discuss-gnuradio] CIC + halfband filter compensation

I hope you will forgive a few naive signal processing questions :) 1) What is the frequency response of the CIC and halfband filters in the USRP? This was addressed long ago on the mailing list (https://lists.gnu.org/archive/html/discuss-gnuradio/2007-05/msg00191.html), but the associated MATLAB

Re: [Discuss-gnuradio] Issue with Pybombs installation

Hi Sumit, Q1 - You might have installed libuhd-dev as a system-wide package using apt-get (if you're using ubuntu). Removing/uninstalling that should work. Q2 - To install other tags/releases of a package in your desired prefix (in your case uhd): 0) Check if the package is already installed

Congratulations, Swapnil and Luca! I'm really excited about your topics, and look forward to seeing your work over the Summer. Good luck, have fun, and happy hacking =) Cheers, Ben On Tue, Apr 24, 2018 at 7:43 AM, Nicolas Cuervo wrote: > Hi all! > > congratulations

[Discuss-gnuradio] coding problem

Recently I made block with simple coding using c++my_demod_block_cb_impl::my_demod_block_cb_impl()  : gr::block("my_demod_block_cb",  gr::io_signature::make(1, 1, sizeof(float)),  gr::io_signature::make(1, 1, sizeof(char)))    {}As you can see I use float as an input,

Hi Marcus, Thank you for your comments. I have tried the other OFDM blocks and it's working. It has better results as well. Best regards, Kurniawan On 24 April 2018 at 18:57, Müller, Marcus (CEL) wrote: > > My questions are should I worry about this warning and try to use >

Re: [Discuss-gnuradio] Transmit Power of USRP B210

The process is simple: You use exactly the settings you want to use later, send a signal of known digital power (i.e. known |x|²), measure the output power with a spectrum analyzer. You take e.g. half that digital power, measure again, to verify you're in the linear region. If you are in the

Re: [Discuss-gnuradio] Transmit Power of USRP B210

The attenuator in the AD9361 transceiver chip used on the B210 is pretty accurate. For a certain frequency, all you need is one measurement. Then the output power will track pretty well with the gain setting. BTW, the TX gain range on the B210 is 0 to 89.8 in 0.2 dB steps. Above around 80 or

Re: [Discuss-gnuradio] Transmit Power of USRP B210

Dear Marcus & Vitt, Thanks for your suggestion. As I am new in this field I don't know how to calibrate spectrum analyser with usrp. Is there any video tutorial or any website link you can provide will be helpful? I have searched on internet but didn't get a thing for calibration. Suggestion
