[Discuss-gnuradio] TX and RX synchronization to control latency
Hello, the recommended way to control latency due to buffers both in software and hardware is to synchronize the TX and RX streams, namely to have a mechanism that emits samples only when samples are received, minus a maximum latency. My naive solution to implement that is this: class synchronize(gr.hier_block2): def __init__(self, fs, delay): gr.hier_block2.__init__(self, self.__class__.__name__, gr.io_signature(2, 2, gr.sizeof_gr_complex), gr.io_signature(1, 1, gr.sizeof_gr_complex)) delay = blocks.delay(gr.sizeof_gr_complex, int(fs * delay)) multiply = blocks.multiply_const_cc(0) add = blocks.add_cc() self.connect((self, 0), (add, 0)) self.connect((self, 1), delay, multiply, (add, 1)) self.connect(add, self) Which is simple enough, but also probably not the most efficient or elegant way. There is a better way of doing it, other than writing a new block, probably based on the delay block?

Re: [Discuss-gnuradio] how to choose tune_delay?
Hi Francois, yes, N210 and later have timed commands abilities, which comes with the feature of metadata containing time stamps; the GNU Radio USRP source is able to evaluate that metadata coming from UHD, and adds stream tags at the right position[1]. Greetings, Marcus [1] https://gnuradio.org/doc/doxygen/classgr_1_1uhd_1_1usrp__source.html#a8ba918061af928ee7c01e7124580eb82 On 04.08.2015 03:21, fquitin wrote: Hi Marcus, Thanks for your comments, as usual, you're being a life-saver (I wasn't aware of the existence of set_command_time/clear_command_time functions, these will be immensely helpfull).

You can try to use use set_auto_dc_offset(False) to make that faster [1]. However, usrp_spectrum_sense is pretty old, and hence can't even make use of stream tags on the GNU Radio side and timed commands on the USRP side, so the lower boundary for delay is the two-way latency between host and device -- which can easily be in the order of tens of milliseconds. I'd personally recommend just going ahead and reimplementing this: * Use the USRP source as usual * use set_time_now (if you don't have a time/PPS source), set_start_time * issue two or three timed tuning commands right at the start (set_command_time, set_rx_freq, clear_command_time) * write a python block that waits for rx_time tags (which automatically get added by the USRP source nowadays) * that block would, upon detection of such a tag, issue the next tune request in line (set_command_time(rx_time+delay), set_rx_freq, clear_command_time) * that block would, after detection of such a tag, first discard a few samples and then calculate your metrics based on the following N samples Best regards, Marcus [1] https://gnuradio.org/doc/doxygen/classgr_1_1uhd_1_1usrp__source.html#adb62a194b0b0761c6a0b4c8c808a20b0 [2] On 03.08.2015 11:11, Francois Quitin wrote: Hi all, I want to retune the frequency of my USRP in Python during runtime.

Re: [Discuss-gnuradio] pybombs difficulty
So I changed the install prefix to /home/username/thesis/target and then deleted the inventory.dat file and removed the previous install prefix folder(this was usr/local, but it actually ended up in usr/local/share, I'm thinking this was a problem because I think there are lingering files). I'm having problems now, I can't remove or update any packages, it states that there is not an inventory file so it creates an empty one and then states there is nothing to do. Is there a way to have it generate a new inventory file? I can't install any packages because they seem to still be in the pybombs folder. Do you have any advice Nathan? My initial reasoning for changing the install prefix to usr/local/ was to enable me to create my own OOT modules and build the tutorial examples. When pybomb's install prefix was in my home directory it kept throwing an error about the CMake files. I tried to change the install prefix locations within those CMake files but that didn't seem to fix my problems. I'm really starting to learn that a little knowledge can be a pretty dangerous thing haha.

In general it's best to avoid using sudo and pybombs together if possible (with the exception of when pybombs asks you for sudo password when using apt-get install). You can either set the prefix to somewhere your user normally has write access to (typically your home directory), or alter permissions of your prefix. As an example, if you were setting your prefix to /opt/gnuradio/pybombs-v3.7.8 the least obtrusive way to do this is sudo mkdir -p /opt/gnuradio/pybombs-v3.7.8 # assuming your user doesn't have write access to /opt/gnuradio you need sudo to mkdir sudo chown myusername:mygroupname /opt/gnuradio/pybombs-v3.7.8 ./pybombs install gnuradio In practice I usually make a group on my machines called 'developer' and add my user to it, then give the developer group ownership or write access (depends on what I feel like when I set up a new machine) to /opt. That lets me write whatever to /opt without sudo (don't forget you need to login after adding your user to group for it to take effect). The same principle can be used with /usr/local or any other directory, but IMHO you should at least make your work an extra layer deep so you can just rm -rf the whole prefix (without root!) and not have much to worry about damaging.

In this case, I'd guess the former. You can adjust the gain directly on the uhd_fft app there with the RX Gain slider. Play with that to see if you can see the signal better. Then use the gain setting as an option to the benchmark scripts. You may also want to adjust the transmit gain setting, as well. But the issue here isn't GNU Radio or USRP. This is now radio. You have to have good enough signal power to receive data, and so you need to adjust the gains of the radio to make that happen.

Re: [Discuss-gnuradio] Error when build GNU Radio using cywin64
Tian Alvin has asked for some further info about my recent Windows build of GnuRadio, I though't I'd reply on-group as I guess there may be a few other masochistic individuale attempting to do this!

I've found a post about the instruction on installing GNU Radio on Windows 64. https://lists.gnu.org/archive/html/discuss-gnuradio/2013-08/msg00284.html Is this the same steps as you were using? If not, could you please share the directions where I can find the guidance? I ended up using multiple sources for help with the build as I had numerous problems. Both the build process, and GnuRadio itself seem to be very sensitive to previously installed software, and since I was building on a general development machine (e.g. multiple versions of Python already installed etc.), things got quite messy. Also it should be noted that my build is currently not perfect. I can only use the WX GUI (i.e. not the QT blocks), the audio output is choppy (this seems to be a common problem and isn't a major issues for me, but if anyone has got a fix for this on Windows I'd be interested to hear it!), and I also haven't enabled some components that I had problems compiling (but that I didn't need), specifically: Version: 3.7.7.1 Components: ## # Gnuradio enabled components ## * python-support * testing-support * volk * sphinx * gnuradio-runtime * gr-ctrlport * gr-blocks * gnuradio-companion * gr-fec * gr-fft * gr-filter * gr-analog * gr-digital * gr-dtv * gr-atsc * gr-audio * * portaudio * * windows * gr-channels * gr-noaa * gr-pager * gr-qtgui * gr-trellis * gr-utils * gr-wxgui ## # Gnuradio disabled components ## * doxygen * gr-comedi * gr-uhd * gr-video-sdl * gr-vocoder * gr-fcd * gr-wavelet * gr-zeromq Some of the resources I used are listed below, but I'd advise caution when referring to them. They are *extremely* useful, (and I'm very thankful that various individuals have taken the time to create them), but some of the facts they quote are not true, or at least not true any more, (not for my 3.7.7.1 build anyway), so take everything with a pinch of salt, including what's in this reply! :-), and confirm everything yourself. https://lists.gnu.org/archive/html/discuss-gnuradio/2013-08/msg00284.html https://www.liamschneider.com/node/9 http://voltronics.blogspot.co.uk/2013/01/gnu-radio-windows-build-guide.html http://code.ettus.com/redmine/ettus/projects/uhd/wiki/GNURadio_Windows?version=94 (Useful info about the prerequisites, this doesn't cover the actual compilation). https://gnuradio.org/redmine/projects/gnuradio/wiki/MingwInstallMain (Again useful for general background info and the list of prerequisites but not the compile itself as I ended up using VisualStudio instead). http://www.lfd.uci.edu/~gohlke/pythonlibs/ (An invaluable resource for Windows binaries of Python modules) There were others I can't remember! I basically Googled gnu radio compile on windows (and other variations), then walked through the results picking off interesting points, comments from blogs, etc. Some general hints from my experience of the build, (when 3.7.8 gets a full release, and if I can find the time, I may attempt the build from scratch again this time documenting the process properly, but for now): 1) There are a *load* of pre-requisite installs before you can start the build. I found determining what is actually required manually (rather than taking the various walk-throughs at face value, particularly about version numbers), to be more beneficial. This process is painful, but repeatedly attempting the CMAKE config (cmake-gui), then finding the required packages one by one is possible, and you gain a much better understanding of the dependences this way. 2) Getting all the correct Python modules installed was a bit of a pain. I'm not a Python person so I had fun with this! pip is your friend here! My current module list is as follows (NB: not all of these may be required for GnuRadio, but most of them were installed one way or another for this build): C:\Python27pip list alabaster (0.7.4) Babel (1.3) cheetah (2.4.4) colorama (0.3.3) docutils (0.12) Jinja2 (2.7.3) lxml (3.4.4) markdown (2.6.2) MarkupSafe (0.23) numpy (1.9.2) pip (7.1.0) pycairo (1.8.10) pycairo-gtk (1.10.0) Pygments (2.0.2) pygobject (2.28.6) pygtk (2.24.0) PyOpenGL (3.1.1a1) PyOpenGL-accelerate

Dear Jaeho, It seems that you didn't install gr-ieee802_15_4 yet. In IEEE802.15.4 category, there is no blocks at all.

I'm having problems now, I can't remove or update any packages, it states that there is not an inventory file so it creates an empty one and then states there is nothing to do. Is there a way to have it generate a new inventory file? I can't install any packages because they seem to still be in the pybombs folder. Do you have any advice Nathan? My initial reasoning for changing the install prefix to usr/local/ was to enable me to create my own OOT modules and build the tutorial examples. When pybomb's install prefix was in my home directory it kept throwing an error about the CMake files. I tried to change the install prefix locations within those CMake files but that didn't seem to fix my problems.

In general it's best to avoid using sudo and pybombs together if possible (with the exception of when pybombs asks you for sudo password when using apt-get install). You can either set the prefix to somewhere your user normally has write access to (typically your home directory), or alter permissions of your prefix. As an example, if you were setting your prefix to /opt/gnuradio/pybombs-v3.7.8 the least obtrusive way to do this is sudo mkdir -p /opt/gnuradio/pybombs-v3.7.8 # assuming your user doesn't have write access to /opt/gnuradio you need sudo to mkdir sudo chown myusername:mygroupname /opt/gnuradio/pybombs-v3.7.8 ./pybombs install gnuradio In practice I usually make a group on my machines called 'developer' and add my user to it, then give the developer group ownership or write access (depends on what I feel like when I set up a new machine) to /opt. That lets me write whatever to /opt without sudo (don't forget you need to login after adding your user to group for it to take effect). The same principle can be used with /usr/local or any other directory, but IMHO you should at least make your work an extra layer deep so you can just rm -rf the whole prefix (without root!) and not have much to worry about damaging.

Re: [Discuss-gnuradio] GRC FFT Plot
Same procedure I outlined before. You need to feed a CW tone (via cable) directly into the USRP and spectrum analyzer, compare spectrum amplitudes, and multiply the USRP samples by 10**(offset_dB/20.0). Noise or a modulated signal makes things more difficult since spectrum analyzer must be put in noise marker mode. Just use a CW tone. Lou Jan wrote Actually, you were right at first madengr. My transmitter is USRP1 with WBX 50-2200 while my receiver is USRP N200 with TVRX2 and spectrum analyzer. Can you give me suggestions on how I can match the amplitude on both the spectrum analyzer and the USRP's? Attached is a screenshot of my experiment on our lab. Using just the GRC Signal Source and Noise Source, I was able to display the desired power amplitude in dBW with less than 10 dB loss by varying the amplitude of each block. For the Signal Source block, the amplitude was 6.31 exp -8 (-144 dBW). For the Noise Source block, the amplitude was 2 exp -8 (-154 dBW). GRC FFT produces -137 dB and -159 dB respectively. Therefore I can say that these dB values in the FFT plot are in dBW. Best, *Gerome Jan M.
