The USRP hardware is sold as test equipment. If you choose to use your USRP hardware and daughterboards to transmit using an antenna, it is your responsibility to make sure you are in compliance with all laws for the country, frequency and power levels in which the device is used. Additionally, some countries regulate reception in certain frequency bands. Again, it is the responsibility of the user to maintain compliance with all local laws and regulations.

+
==Will the power supply work in country X? Is it approved in country X? What are the power requirements?==
+
 
+
All current USRP software defined radios require 6V at 3A. The USRP power supply shipped with all USRP software defined radios  has the following specifications:
+
 
+
*Input: 90-264 Vac at 50 to 60Hz
+
*Output: 6Vdc at 3A
+
*Interchangeable input plugs provided: NA, EU, UK, AU
+
*Safety Approvals: UL/cUL, GS, CE, FCC, RCM
+
*EMC/EMI: FCC class B, CE, VCCI class II
+
 
+
The DC plug is a 2.1mm center conductor, 9.5mm barrel, 5.5mm outer diameter standard plug.
+
 
+
The USRP power supplies accept 90-264Vac at 50 or 60Hz, and come with interchangeable plugs that allow use in most parts of the world.
+
+
==What USRP models are compatible with the GPSDO kit?==
+
The GPSDO kit is compatible with a specific set of USRP models and revisions. Compatibility is determined by hardware characteristics, and therefore incompatible models cannot be upgraded to be made compatible. Before purchasing a GPSDO kit please verify whether it will be compatible with the USRP device you intend to use with it. The compatible models and revisions are:
+
 
+
===USRP N200/N210===
+
 
+
*USRP N200 Rev 2.0
+
*USRP N200 Rev 3.0
+
*USRP N200 Rev 4.0
+
 
+
*USRP N210 Rev 2.0
+
*USRP N210 Rev 3.0
+
*USRP N210 Rev 4.0
+
 
+
===USRP E100/E110===
+
 
+
*USRP E100 Rev 4.0
+
*USRP E110 Rev 4.0
+
 
+
Please note the USRP hardware revision is on the label on the back of the unit.
+
 
+
The GPSDO kit is not compatible with the USRP1, USRP2, USRP B100 and any revision of the USRP N200/210 and E100/110 series not listed above.
+
 
+
==Are all daughterboards compatible with all USRP motherboards?==
+
 
+
All daughterboards are compatible with all USRP models except for the first 500 USRP1 software defined radios manufactured in 2005. At that time all daughterboards had an onboard local oscillator so the USRP1 did not provide a clock signal required by most of the current daughterboards. The only daughterboards currently compatible with the first 500 USRP1 are the BasicRX, BasicTX, LFRX and LFTX as they do not require a clock signal.
+
 
+
To identify if you have one of the first 500 USRP1 devices, please refer to the serial number as it will be between 1 and 500.
+
  
Although unsupported, a workaround exists and can be accessed on the following page: [http://gnuradio.org/redmine/projects/gnuradio/wiki/USRPSerialBelow500 USRP Serial Below 500 on GNU Radio].

== Are there any license requirement for using any USRP equipment? ==
  
 +
If you choose to use your USRP hardware to transmit any radio signal, it is ''your'' responsibility to make sure your use is in compliance with all laws and regulations for the country in -- and frequency and power levels at -- which the USRP is used. We strongly recommend that any USRP user determine what license may be required and what restrictions may apply before attempting to transmit and/or receive any radio signals. It is the sole responsibility of the user to maintain compliance with all local laws and regulations.

USRP hardware is sold as "test and measurement equipment". Each country has laws and regulations governing the transmission and reception of radio signals. Most if not all countries require a license to transmit certain radio signals and many have laws and regulations governing reception. Each USRP user is ''solely'' responsible for insuring their USRP system use is in compliance with all such laws and regulations, including but not limited to obtaining a license and keeping power levels within legal limits for any specific radio frequency.

How do I get started?

For the UHD Getting Started documentation please refer to the UHD Manual.

For the GNU Radio Getting Started documentation please refer to the GNU Radio wiki.

Do you have antennas to match your daughterboards?

Yes, we have antennas for nearly every daughterboard which we sell. Please see the ordering page for pictures and specifications at the following links:

What operating systems are supported?

The UHD (USRP Hardware Driver) supports all Ettus Research hardware on the following operating systems:

  • Linux (any distribution should work, but primarily Ubuntu, Fedora, and CentOS, and specifically the current and immediate prior versions)
  • Mac OS X 10.4 or newer, macOS 11 or newer, macOS 26 or newer
  • Microsoft Windows 7, 8, 10, 11

Primary development for UHD is done on Linux.

Are design files available with the boards that may aid in further prototyping?

For detailed design files such as schematics and certain other more in-depth USRP documentation submit a request via the Support Request Manager.

Are there any license requirement for using any USRP equipment?

If you choose to use your USRP hardware to transmit any radio signal, it is your responsibility to make sure your use is in compliance with all laws and regulations for the country in -- and frequency and power levels at -- which the USRP is used. We strongly recommend that any USRP user determine what license may be required and what restrictions may apply before attempting to transmit and/or receive any radio signals. It is the sole responsibility of the user to maintain compliance with all local laws and regulations.

USRP hardware is sold as "test and measurement equipment". Each country has laws and regulations governing the transmission and reception of radio signals. Most if not all countries require a license to transmit certain radio signals and many have laws and regulations governing reception. Each USRP user is solely responsible for insuring their USRP system use is in compliance with all such laws and regulations, including but not limited to obtaining a license and keeping power levels within legal limits for any specific radio frequency.
