Driver UHD and GNURadio software installation

This file provides instructions for installing the UHD (USRP Hardware Driver) and GNURadio software on a Windows x64 system. It includes links to the necessary drivers and packages from Ettus Research, as well as steps for setting up the environment variables required for the installation. This document is intended to guide users through the process of configuring their system to work with UHD and GNURadio on a Windows OS.

For Windows x64

Links UHD-USRP:

Set Drivers:

On User variables > Path: Add path of package UHD
Variable name: Path
Variable value: C:\Program Files\UHD
On System variables: Create path of Driver USRP
Variable name: UHD_IMAGES_DIR
Variable value: C:\Program Files\UHD\share\uhd\images

Example set path

  • Copy the file "libusb-1.0.dll" to the path C:\Windows\System32

  • Test the installation in CMD with USRP connected:

    >> uhd_find_devices

    UHD find devices


Using GNU Radio:

Download directly GNURadio Radioconda (Recomended) and install package radioconda.exe

Installing packages whit conda using terminal

(Run CMD or PowerShell as administrator)

Example: adding packages for use uhd package on Jupiter Noteboook for VS Code:

>> cd C:\ProgramData\radioconda\Scripts
>> conda.exe install ipykernel --update-deps

  • Modifying conda executables for convenience:
    (Only if we have other versions of python already installed)

    Change To
    C:\ProgramData\radioconda\Scripts\conda.exe C:\ProgramData\radioconda\Scripts\radioconda.exe
    C:\ProgramData\radioconda\Scripts\conda-script.py C:\ProgramData\radioconda\Scripts\radioconda-script.py
    and Add Environment variable C:\ProgramData\radioconda\Scripts

Example: Using UHD python API 🔝

Example test for Rx:

import uhd
import numpy as np

usrp = uhd.usrp.MultiUSRP()

# Model: B200
# serial number: 31BA1B2

num_samps = 10000 # number of samples received
center_freq = 100e6 # Hz
sample_rate = 1e6 # Hz
gain = 50 # dB

usrp.set_rx_rate(sample_rate, 0)
usrp.set_rx_freq(uhd.libpyuhd.types.tune_request(center_freq), 0)
usrp.set_rx_gain(gain, 0)

# Set up the stream and receive buffer
st_args = uhd.usrp.StreamArgs("fc32", "sc16")
st_args.channels = [0]
metadata = uhd.types.RXMetadata()
streamer = usrp.get_rx_stream(st_args)
recv_buffer = np.zeros((1, 1000), dtype=np.complex64)

# Start Stream
stream_cmd = uhd.types.StreamCMD(uhd.types.StreamMode.start_cont)
stream_cmd.stream_now = True
streamer.issue_stream_cmd(stream_cmd)

# Receive Samples
samples = np.zeros(num_samps, dtype=np.complex64)
for i in range(num_samps//1000):
    streamer.recv(recv_buffer, metadata)
    samples[i*1000:(i+1)*1000] = recv_buffer[0]

# Stop Stream
stream_cmd = uhd.types.StreamCMD(uhd.types.StreamMode.stop_cont)
streamer.issue_stream_cmd(stream_cmd)

print(len(samples))
print(samples[0:10])

UHD error 🔝
