[USRP-users] Web server on E310

Hi, I’m currently running a C++ application on the E310 which sends/receives some data to a client through TCP. Instead, I’d like to run a web server on the E310 so that a client could connect with a browser to a site with a basic GUI, and the C++ program would interact with the server instead o

[USRP-users] TwinRx not recieving waveform

Hello,I am fairly new to usrp's and i am having troubles getting a waveform from a x310 with one TwinRX daughterboard acting as a receiver. I am using 2 signal generators to generate the waveform. My UHD version is 3.10.something (the newest auto-downloaded version). I am using GNU-radio to show

[USRP-users] problem with RFNoC probing

I am not sure what is going on, but while working on my new RFNoC block, I can't probe my X310 anymore. When I do, I get this error: [INFO] [CORES] Performing timer loopback test... [ERROR] [UHD] Exception caught in safe-call. in virtual ctrl_iface_impl::~ctrl_iface_impl() at /home/jmat/rfn

Re: [USRP-users] issue with rfnoc fft size

You'll need to make certain that the MTU on your network card supports the required frame sizes for your FFT. On 1GiGe, you're unlikely to be able to support greater than 1024-bin FFTs, since most cards won't do jumbo frames larger than 9000 bytes. On 2017-07-17 11:38, Sanjoy Basak via USRP-use

Re: [USRP-users] issue with rfnoc fft size

Hi, Your Ethernet packet size has to be large enough to fit the entire FFT output in a single packet. Try setting your MTU to 9000. Jonathon On Mon, Jul 17, 2017 at 8:38 AM, Sanjoy Basak via USRP-users < usrp-users@lists.ettus.com> wrote: > Hello experts, > I am trying to use RFNoc fft examples

[USRP-users] issue with rfnoc fft size

Hello experts, I am trying to use RFNoc fft examples (rfnoc_fft.grc). I started with the gr-ettus examples. However, I am having some problems with the fft size. In the grc block, I find the option to choose 4096 fft size. However, with hardware I could only work fft size 128 and 256. If I use 512/

Re: [USRP-users] Removing the whole LO signal when transmitting

Hello Brais, The gain values for USRPs are indexed from 0 dB gain being minimum gain up to the device's maximum. Usually this means that 0 dB of gain is actually a large amount of attenuation or loss through the RX chain. The same is true for TX. It doesn't surprise me that you are seeing those va

Re: [USRP-users] Removing the whole LO signal when transmitting

Ok, I understand! Also I have to configure a rx_gain of 60 dB, and a tx_gain of 10 dB If I want to reconstruct the transmitted signal to the very same power level I received it. The scheme would be: ~~~ signal_generator (QPSK at -60 dBm) -> cable(0.3 dB attenuation) -> rx_usrp -> tx_usrp -> cable
