If you run
tx_waveforms --power -20 [other args]
it will try to set the out power to -20 dBm. The signal amplitude is
factored in, so changing --ampl will not change the actual TX power
unless it causes clipping, or becomes too low.
If the USRP does not support setting a power, the program will terminate
early. If it does support setting a power, but can't reach the requested
power, it will coerce, and print the actual, available power.

USRP Hardware Driver (UHD™) Software
Welcome to the UHD™ software distribution! UHD is the free & open-source software driver and API for the Universal Software Radio Peripheral (USRP™) SDR platform, created and sold by Ettus Research.
UHD supports all Ettus Research USRP™ hardware, including all motherboards and daughterboards, and the combinations thereof.
Documentation
For technical documentation related to USRP™ hardware or UHD system design, check out the UHD and USRP Manual. That is where you can find Installation Instructions, help on how to build UHD from source on different platforms, development guidelines and reference documentation as well as device usage guidance.
Additionally, be sure to check out the Ettus Research FAQ, and the Knowledge Base for useful application notes and tutorials.
OS Support
UHD is primarily developed on Linux, but we also test and support the following operating systems.
- Linux (Fedora and Ubuntu)
- Mac OS X (Intel)
- Windows 7
Other operating systems will most likely work, too, but are not officially supported.
Applications
UHD can be used to build stand-alone applications with USRP™ hardware, or with third-party applications. Some common toolkits / frameworks are:
- GNU Radio
- NI LabVIEW
- MathWorks Simulink
- REDHAWK
- OpenBTS GSM
- Osmocom GSM
- Amarisoft LTE
- Software Radio Systems LTE
Directories
host/
The source code for the user-space driver.
mpm/
The source code for the module peripheral manager (MPM). This is code that is run on embedded devices.
firmware/
The source code for all microprocessors in USRP hardware.
fpga/
The source code for the UHD FPGA images.
images/
This contains the package builder for FPGA and firmware images. We provide other tools to download image packages, the scripts in here are mainly relevant for UHD maintainers and -developers.
