How to integrate usrp n200 through redhawk 2.0.7?

问题 I am trying to transmit a signal through usrp in redhawk 2.0.7. For that I made a simple waveform and export it to target SDR in Redhawk explorer view. After that I have a made a node and include usrp uhd device in that node. I have exported this node project to target sdr. After that I have launched domain manager by right clicking on target sdr. By doing so, both GPP and usrp started in device manager. But when I launched waveform, it gives me error. Failed to create application. Failed to

While loop is taking too much time to execute, also within the loop elapsed time is large

问题 I’m working on a radar project using USRP N210 with UBX-40 daughterboard using MATLAB. I am facing a problem when I run the code for receiving the echo of the transmitted pulse. It is taking 4 seconds for the board to start receiving and collecting first sample, which doesn’t suit at all my case. After the first sample, receiving elapsed time for the other echoes is in milliseconds which not good because, echoes in radars should be received within microseconds or less and not seconds and

UHD USRP device lacks capacity

问题 I'm using Redhawk 1.10.0 on a CentOS 6.5 machine 64 bit and USRP b100 with UHD driver 3.7.2. The USRP b100 is recognized correctly by the system. It is a USB device. I downloaded the latest version of UHD_USRP Device ver. 3.0 for REDHAWK and I created a Node including a GPP and a UHD_USRP devices. The Node is started without any problem but when I run a simple waveform to read data from the USRP as a RX_DIGITIZER I got the following error: Failed to create application: usrp_test_248_173059195

问题 I'm running REDHAWK 1.10 on a CentOS6.5 VM. I have the connection set to bridged and can locate the USRP by its IP address using: uhd_find_devices --args="addr= <ip address>" I have a usrp2 with serial E5R1AS2UP Here are the steps I take: $ sudo $OSSIEHOME/bin/cleanomni $ nodeBooter -D -debug 5 $ nodeBooter -d <location to USRP_UHD node>.xml -debug 5 I have also run these commands as requested by the USRP: sudo sysctl -w net.core.rmem_max=50000000 sudo sysctl -w net.core.wmem_max=1048576

FFT in non-flowgraph centered application different from flowgraph centered apps like uhd_fft

由 人走茶凉 提交于 2019-12-24 15:04:01
问题 I've written a small GNU Radio program to capture and plot FFT data from the USRP N210. To avoid locking up my GUI (matplotlib and wxpython), I am only running the flowgraph after the GUI reports that it's idle. In order to do that kind of timing, I'm using a non-flowgraph centered approach, introduced in the GNU Radio Tutorial. Essentially, I have a main loop that looks like this (pseudocode): topblock.set_usrp_freq() while True: topblock.run() data = topblock.vector_sink.data() thread-safe

问题 The N210 is connected to the RF frontend, which gets configured using the GNU Radio Companion. I can see the signal with the FFT plot; I need the received signal (usrp2 output) as digital numbers.The usrp_sense_spectrum.py output the power and noise_floor as digital numbers as well. I would appreciate any help from your side. 回答1: Answer from the USRP/GNU Radio mailing lists: Dear Abs, you've asked this question on discuss-gnuradio and already got two answers.

voltage pulse from USRP when using simple GNU Radio flowgraph from Python

问题 This is a follow-up to my earlier question: FFT in non-flowgraph centered application different from flowgraph centered apps like uhd_fft In an attempt to better clarify the issue, I've boiled my code down to about ~30 LOC and have removed as much processing out of the flowgraph as possible. The issue that I'm having is that, although the USRP is tuned to a frequency only once, each run of the flowgraph has about 70 ms of junk data. I'm fully aware that a certain amount of "junk" samples are

REDHAWK UHD device usage

问题 I have successfully installed the UHD device along side REDHAWK version 1.8.3. It isn't obvious to me how to connect a component in a waveform to a device being managed by a device manager. I am also unclear on the interplay between the IDL interfaces and the data ports on the USRP device. I was unable to find a trivial example to send and receive waveform that utilizes the USRP device (e.g. a signal generator component sending a sine wave to the USRP). Does anyone have experience with this

问题 I got this error when I tried to run my gnuradio python program through Flask webserver. I am getting this error when I added my USRP b200 lines of code into my original "working/healthy" code. In this program I am trying to control the variables of my code through slider widgets in my Flask webserver. Again, the USRP that I am using works just fine whenever I I run any app in my GnuRadio software itself. But when I try it through Flask it runs for a second or 2 then crashes. Any assistance
