Good morning Sir, I would like to calculate sensitivity of USRPN210 Radio module by using gnuradio tool..I working on that ..I tried lot sir..please help me and please forward .GRC file if u have sensitivity measuring...in specification his given -110dbm but practically I want calculate and how to send -80dbm power to antenna..please guide me sirThanks & Regards, Suresh T, Navstar Integrated Systems Pvt ltd, 9866212494

That's the most reliable way to handle such potentially in-depth queries such as yours. As a quick reply without knowing more specifics, are you using the "hier_block2" for the base class for your main block? If so, then you can't do signal processing within this block; all a "hier_block2" block is good for is encapsulating other blocks, connecting them internally as well as to the "hier_block2"s input(s) and output(s); no "work" here! >From the debug printout, likely candidates for this issue would be the block "fft_vxx" or "ieee802_11_soft_frame_equalizer_dc".

I partially resolved this by uninstalling UHD and GRC, and using the latest PyBOMBS to compile from source both UHD and GRC. The good news is that after installing the correct FPGA image, GRC runs. Unfortunately it is not operating correctly. GRC is throuwing codes Gt, the simple generate a cosine tone, send it to the Ettus X310, then loop it back to the receiver for display seems to only show LO leakage at 0 Hz. Additionally GRC will not properly end, and I must force an exit. Attached is the console output (text file). It looks like I have some files from the old install that are interfering with the new GRC install. I'm not sure where to look to erase them if so. Any other idea's what is the issue?

As far as I know gr-uhd just makes use of the system UHD install. Perhaps you have two different locations that UHD is installed to? You could double check that you don't have libuhd.so in /usr/local/lib and /usr/lib at the same time. I'd suggest updating the radios to the current firmware with uhd_image_loader, power cycling them, and then trying again. > > Good luck! > > -Dave > > On Thu, Sep 20, 2018 at 5:36 PM John_w_g <john_...@protonmail.com> wrote: > >> I am using Ubuntu 18.04 and the only listed GRC version in the ppa is version 3.13.0.1 >> >> I have an Ettus x310 and have downloaded the correct FPGA image and verified correct operation with uhd_usrp_probe. >> >> I have GRC 3.7.11 installed and when I attempt to access the x310, I get an incompatible FPGA version. >> >> First question is what is the correct GRC version to work with this UHD version? >> >> Second question as a relatively new Linux user, I really don't want to compile source code.
