Test and Verify the Operation of the USRP
Once the software tools are installed on the host computer, or using the LiveUSB SDR Environment, verify the
correct operation of the USRP by running the various utility programs on the host computer. More information
is available at “Getting Started”, on the USRP B200mini/B200mini-i/B205mini-i Product Page on the Ettus
Research Knowledge Base.
Proper Care and Handling
All Ettus Research products are individually tested before shipment. The USRP B200mini/B200mini-i/B205mini-
i is guaranteed to be functional at the time it is received by the customer. Improper use or handling of the
USRP B200mini/B200mini-i/B205mini-i can easily cause the device to become non-functional. Listed below are
some examples of actions which can prevent damage to the unit:
•
Never allow metal objects to touch the circuit board while powered.
•
Always properly terminate the transmit port with an antenna or 50
Ω
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.
Never apply more than -15dBm of power into any RF input!
Use extreme caution when connecting the transmit port to the receive port in a loopback
configuration. The transmitter is capable of output powers that can damage the receiver un-
less necessary precautions are taken. The use of a 30dB attenuator is strongly recommended
when using in a loopback configuration.
The USRP B200mini/B200mini-i/B205mini-i is a piece of test equipment that can transmit
and receive on many frequencies. Each country has important legal implications to consider
concerning radiated RF energy. See “Legal Considerations” in this document before using
this device!
Technical Support and Community Knowledge Base
Technical support for USRP hardware is available through email only. If the product arrived in a non-functional
state or you require technical assistance, please contact [email protected]. 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.
