To operate the device you will need to install the RF daughterboards and supplied bulkhead cables. After installation, the daughterboards and cables should be secured with the hardware provided. The device must be powered off when installing daughterboards to avoid potential damage.
Release 3. It is recommended to use the latest stable version of UHD that is available. Once the software tools are installed on the host computer, or using the Live SDR Environment , verify the correct operation of the USRP by running the utility programs on the host computer. Technical support for USRP hardware is available through email only.
Choose the instructions for the OS on the host computer. When connecting to an Ethernet-based radio, a second NIC is recommended for the host computer to remain simultaneously connected to the radio and a network or the Internet. This value is used for the radio IP address throughout the setup instructions. If your radio has a different IP address, modify accordingly. Make sure you have at least one microSD card reader and one writable microSD card.
The instructions below assume a Linux host. First, connect to the APU serial console at a baud rate of Boot the device, and stop the boot sequence by typing noautoboot at the prompt. Then, run the following command in the U-boot command prompt:. You should see a spinning indicator on the console, which indicates the gadget is active.
Your computer should recognize the X as a mass storage device, and you should see an entry in your kernel logs dmesg that looks like this:.
You can obtain the latest filesystem image by running:. Mender is a third-party software that enables remote updating of the root file system without physically accessing the device see also the Mender website.
Mender can be executed locally on the device, or a Mender server can be set up which can be used to remotely update an arbitrary number of USRP devices. Mender servers can be self-hosted, or hosted by Mender see mender. When updating the file system using Mender, the tool will overwrite the root file system partition that is not currently mounted note: the onboard flash storage contains two separate root file system partitions, only one is ever used at a single time.
Any data stored on that partition will be permanently lost, including the currently loaded FPGA image. After updating that partition, it will reboot into the newly updated partition. Only if the update is confirmed by the user, the update will be made permanent.
This means that if an update fails, the device will be always able to reboot into the partition from which the update was originally launched which presumably is in a working state.
Another update can be launched now to correct the previous, failed update, until it works. To initiate an update from the device itself, download a Mender artifact containing the update itself. These are files with a.
This procedure will take a while. After mender has logged a successful update, reboot the device:. If the reboot worked, and the device seems functional, commit the changes so the boot loader knows to permanently boot into this partition:.
To identify the currently installed Mender artifact from the command line, the following file can be queried:. If you are running a hosted server, the updates can be initiated from a web dashboard. From there, you can start the updates without having to log into the device, and can update groups of USRPs with a few clicks in a web GUI.
The dashboard can also be used to inspect the state of USRPs. This is a simple way to update groups of rack-mounted USRPs with custom file systems. This interface is agnostic of FPGA image flavor. The internal network interface is configured with a static address: Jump to: navigation , search.

Never apply more than dBm of power into any RF input. Always use at least 30dB attenuation if operating in loopback configuration. These GPIO signals can serve the following functions: Control of external devices, such as power amplifiers and RF switches Provide output signals that can help with debugging Provide observables to be analyzed by oscilloscopes or other external equipment Accept input from external devices for local, software-based triggering Implement a protocol line such as SPI or I2C.
