FAQ
What are the available resources on the FPGA?
The available resources on the FPGA will vary depending on the code written for it. Based on the 27 March 2012 FPGA code build, the following resources are available:
USRP2 (Xilinx Spartan 3 - XC3S2000 FPGA)
- General Logic
- Memory: 3% free
- DSP Resources: The FPGA does not have DSP resources
Proper Care and Handling
All Ettus Research products are individually tested before shipment. The USRP™ is guaranteed to be functional at the time it is received by the customer. Improper use or handling of the USRP™ can easily cause the device to become non-functional. Listed below are some examples of actions which can prevent damage to the unit:
- Never apply more than -15 dBm of power into any RF input.
- Never allow metal objects to touch the circuit board while powered.
- Always properly terminate the transmit port with an antenna or 50Ω load.
- Always handle the board with proper anti-static methods.
- Never allow the board to directly or indirectly come into contact with any voltage spikes.
- Never allow any water, or condensing moisture, to come into contact with the boards.
- Always use caution with FPGA, firmware, or software modifications.
- Always use at least 30dB attenuation if operating in loopback configuration
Technical Support and Community Knowledge Base
Technical support for USRP hardware is available through email only. If the product arrived in a nonfunctional state or you require technical assistance, please contact support@ettus.com. Please allow 24 to 48 hours for response by email, depending on holidays and weekends, although we are often able to reply more quickly than that.
We also recommend that you subscribe to the community mailing lists. The mailing lists have a responsive and knowledgeable community of hundreds of developers and technical users who are located around the world. When you join the community, you will be connected to this group of people who can help you learn about SDR and respond to your technical and specific questions. Often your question can be answered quickly on the mailing lists. Each mailing list also provides an archive of all past conversations and discussions going back many years. Your question or problem may have already been addressed before, and a relevant or helpful solution may already exist in the archive.
Discussions involving the USRP hardware and the UHD software itself are best addressed through the usrp-users mailing list at http://usrp-users.ettus.com/.
Discussions involving the use of GNU Radio with USRP hardware and UHD software are best addressed through the discussgnuradiomailing list at https://lists.gnu.org/mailman/listinfo/discussgnuradio.
Discussions involving the use of OpenBTS® with USRP hardware and UHD software are best addressed through the openbtsdiscussmailing list at https://lists.sourceforge.net/lists/listinfo/openbtsdiscuss.

Legal Considerations
Every country has laws governing the transmission and reception of radio signals. Users are solely responsible for insuring they use their USRP system in compliance with all applicable laws and regulations. Before attempting to transmit and/or receive on any frequency, we recommend that you determine what licenses may be required and what restrictions may apply.
