Re: Promblems with gr-air-modes in gnuradio 3.10

Hi Cinaed,

thank you for your answer, It seems like modes_rx (gr3.9 branch) under 
GNU Radio 3.10 hangs somewhere on startup. @willcode4  will try to debug 
it.


have a good day.

Sometimes OOT modules which work on 3.9 work on 3.10 - sometimes they 
don't.


It's possible your version gr-air-modes has a different author from 
git hub version above.


And I don't have a version of 3.9 either so I can't test it on 3.9 .

So I installed this version in my computer, the installation was 
successfull however when I execute rx_modes I do not receive any

You are probably missing some development dependency installed on your system. 
How did you install gnuradio 3.10.4 - from the ppa, from source, ...?

This Boost::data_time dependency is a bit strange. Have you tried adding this 
to your OOT module?

Maximum sample rate for two channels

[isaac mario tupac davila]

Hello community

I'm Isaac. I'm trying to receive a signal with two channels using an USRP
N200 and a Basic RX.
I'm setting the sample rate of each channel to 20MSp/s, but what I obtain
is: The total sum of rates (40.00 MSps on 2 channels) exceeds the
maximum capacity of the connection, causing overflow (O) in the acquisition.

So, How do I know which is the maximum capacity for two channels? Why is it
not possible to acquire two channels with a sample rate of 20MSp/s in each
one if I can acquire one channel with 20MSp/s?

Thanks in advance

Isaac T.

The maximum possible bit-rate for a 1GiGe connection is 1Gbit/sec.

The absolute most you can push over such a connection with the N200 is 
25Msample/second--with 16-bit I and Q.


If you move to 8-bit samples, using "otw_format=sc8" in your device 
arguments, you can move up to 50Msps over

  that same connection.

This is basically just the maximum delivered rate of a 1Gbit 
connection.  So, one channel at 25Msps or two channels at 12.5Msps,
  or if you're using sc8 "wire" format, 50Msps for one channel and 
25Msps for two channels.

RE: Problems with gr-modtool on Ubuntu 20.04 (gnuradio 3.10.4)

[Michael Matthews]

Hi Vasil,

I installed gnuradio from the ppa. Specifically, I did:

    $ sudo add-apt-repository ppa:gnuradio/gnuradio-releases
    $ sudo apt-get update
    $ sudo apt-get install gnuradio python3-packaging
    $ sudo apt install libiio-dev libad9361-dev libspdlog-dev python3-packaging python3-jsonschema
    $ sudo apt-get install gnuradio-dev cmake libspdlog-dev clang-format

The instillation wiki does note that the python packaging module might need to be installed using pip for 3.10. Running that installation just tells me that "the requirement is already satisfied" so I believe it is already up to date. It is also mentioned on Ubuntu 18.04 there is an issue with gr_modtool when installed from the PPA, but it says the issue is not appearing for Ubuntu 19 and later.
  
As far as the date_time dependency is concerned, I am unsure where that is being used. I did not import it myself. The Cmake was procedurally generated using the gr-modtool, following the tutorial exactly. The tutorial is fairly simple, adding a boolean selector, which determines whether two input values should either be multiplied or divided with:

{
    auto in0 = static_cast(input_items[0]);
    auto in1 = static_cast(input_items[1]);
    auto out = static_cast(output_items[0]);

    for (int index = 0; index < noutput_items; index++) {
    if (_selector) { out[index] = in0[index] * in1[index]; }
    else{ out[index] = in0[index] / in1[index]; }
    }

    // Tell runtime system how many output items we produced.
    return noutput_items;
}

Thank you for your help,

Yep, gr-air-modes hasn't been built, installed, or tested by me. Needs the
usual rebuild-from-gr-modtool, and I haven't gotten around to it.
