Mismatched MTU values on either the Host or E320 may cause flow control errors. A direct connection to the microcontroller can be used to hard-reset the device without physically accessing it (i.e., emulating a power button press) and other low-level diagnostics. Configure your Host's 10 Gb Ethernet interface as shown below. The difference between the N320 and the N321 is in its LO sharing capability. To start it, simply log on to the device and run: To permanently enable it at every boot, run (this won't by itself launch the salt-minion): To make use of Salt, both the device needs to be configured (the "minion") and, typically, a server to act as the Salt master. Discussions involving the use of GNU Radio with USRP hardware and UHD software are best addressed through the discuss-gnuradio mailing list at https://lists.gnu.org/mailman/listinfo/discussgnuradio. The USRP N320 is a networked software defined radio that provides reliability and fault-tolerance for deployment in large scale and distributed wireless systems. The rx_ascii_art_dft utility is a simple console based, real-time FFT display tool. REF: Indicates a lock to the reference clock. If this release fails to work in some way, then try the maintenance branch of the latest stable version. The aforementioned SFP tests will load the AA FPGA image and use Aurora to run the BER tests on the SFP ports. You should not try to source more than 5mA per pin. To use your Universal Software Radio Peripheral (USRP), you must have software tools correctly installed and configured on your host computer. The micro SD card used can be the original SD card shipped with the device or another one that is at least 16 GB in size. From there, you can start the updates without having to log into the device, and you can update groups of USRPs with a few clicks in a web GUI. Note that it will always come up in a default state, which can be changed by modifying the configuration file in /etc/uhd/mpm.conf (see also Configuration Files), such as this: If you prefer not to have the device initialize on boot, but rather have a fast boot time, add the line skip_boot_init=1 to your /etc/uhd/mpm.conf file. By setting the log level to DEBUG you will be able to observe the exact settings that cause fast vs. slow re-initialization. For Network Mode: A host computer with an available 1 or 10 Gigabit Ethernet interface for sample streaming. We provide the following flavors of FPGA images in our default image set: The N320 has an additional QSFP port, and therefore has additional FPGA flavors (AQ, XQ). This will force a full initialization of the device the first time a UHD session is started, rather than during device boot. Insert the RJ45 SFP+ adapter into SFP Port 0 . A step-by-step guide for doing this is available at the Building and Installing the USRP Open-Source Toolchain (UHD and GNU Radio) on Linux, OS X and Windows Application Notes. NOTE: The HG FPGA image must be loaded for SFP Port 0 to operate at 1Gb speeds. In order to better use the high available rates, the N320/N321 devices have an additional QSFP+ connector on the back panel which can be used for streaming data to and from the radios. Note that updating the FPGA image will force a reload of the FPGA, which will temporarily take down the SFP network interfaces (and temporary settings, such as applied via ifconfig on the command line, will be lost). The entire root file system (Linux kernel, libraries) and any user data are stored on this SD card. The dashboard can also be used to inspect the state of USRPs. If the decimation or interpolation factor exceeds 256, then it must be evenly divisible by 4. Once you have successfully setup a management interface and streaming interface, you can now verify the devices operation using the include UHD utilities. If you have an internet connection, you can use git to pull it directly from the Ettus repository (all commands are run on the device itself, inside the home directory): You can also SSHFS it from another computer: Now, create a build directory and use the regular cmake/make procedure to kick off a build. A more detailed description of the calibrations can be found in the AD9371 user guide, see chapter "Quadrature Error Correction, Calibration, and ARM Configure your Host's Ethernet adapter as shown below. Please note that modifications to the FPGA are made at the risk of the user, and may not be covered by the warranty of the device. It can also be run over a serial console connection, although this is not recommended, as the formatting may not render correctly. Additional information on Sample Rates can be found here in the UHD Manual: http://files.ettus.com/manual/page_general.html#general_sampleratenotes. This is a high performance SDR that uses a unique RF design by Ettus Research to provide 2 RX and 2 TX channels in a half-wide RU form factor. The E320 Full Enclosure version must be opened with the included Torx wrench. Insert the RJ45-to-SFP+ adapter into the SFP+ Port. The Verilog code for the FPGA in the USRP N3xx is open-source, and users are free to modify and customize it for their needs. Users are solely responsible for insuring they use their USRP system in compliance with all applicable laws and regulations. The exact device node you should attach to depends on your operating system's driver and other USB devices that might already be connected. This can be used to debug kernel or bootloader issues more efficiently than when logged in via SSH. When updating the file system using Mender, the tool will overwrite the root file system partition that is not currently mounted. To test the PPS input, you can use the following tool from the UHD examples: As of December 1st, 2010 all Ettus Research products are RoHS compliant unless otherwise noted. The marquee feature of UHD 4.1 is support for the new NI Ettus USRP X410, a new generation of radio providing the highest performance of any USRP to date. ; connected before turning the device on if it set to external here: $ cmake -Wno-dev -DCMAKE_TOOLCHAIN_FILE=../cmake/Toolchains/oe-sdk_cross.cmake \-DCMAKE_INSTALL_PREFIX=/usr -DENABLE_GR_VOCODER=OFF -DENABLE_GR_ATSC=OFF \, -DENABLE_GR_DTV=OFF -DENABLE_DOXYGEN=OFF ../ # Append any CMake options you desire, rx_gain_profile=default_rf_filter_bypass_always_off, tx_gain_profile=default_rf_filter_bypass_always_on, rx_band_map=0.0;431e6;601e6;1051e6;1601e6;2101e6;2701e6, tx_band_map=0.0;723.18e6;1623.18e6;3323.18e6. To operate the device you will need to install the RF daughterboards and supplied bulkhead cables. The power level of the reference clock cannot exceed +10 dBm. The CPU is clocked at 800 MHz (speedgrade 2). The valid decimation rates are between 1 and 1024. The devices labeled "USB_to_UART_Bridge_Controller" are the devices that offer a serial prompt. For example, if an operator would like to reset the root password on multiple devices, or install custom software, this tool might be a suitable choice. Without access to a router management interface, you can identify the IP address by connecting to the ARM CPU via Serial Console as detailed in the section above and running the command ip a: If you do not have access to a network with a DHCP server, you can create one using the Linux utility dnsmasq: NOTE: Modify the value to match the interface you would like to create a DHCP server on. If only a clock reference is available, it is possible to derive an internal PPS signal from the reference (which will allow devices to share a frequency, but not a time reference). LSB is for GPIO 0. Finally, a White Rabbit-compatible FPGA must be loaded. usrp->set_tx_filter(tx_names[0], filter, chan); , TX TX Halfband 2x MCR , > IQ Offset >DC Offset > Interpolator > DAC , Compensation Compensation (47 taps) , RFNoC , Block , RX RX Halfband 2x MCR , < IQ Offset below and run the command: Thus, for the value noted above (autoboot is already disabled, so this command doesn't actually change anything): If setting this flag does not allow autoboot control on the USRP E320, then the device boot firmware needs to be updated. To test the SFP Port 0 connection, ping the device at address 192.168.10.2 from the host, as shown below: 5. Every country has laws governing the transmission and reception of radio signals. The N3xx-series are devices based on the MPM architecture (see also: The Module Peripheral Manager (MPM) Architecture). See also Section The SD card. The White Rabbit image is provided as a default image. The USRP N320 includes a Trusted Platform Module to enable security features such as file encryption. // ATR on pin 1 is off when not receiving: // Set the Analog Bandwidth to be 20 MHz wide, // Get the first filter and print out the filter properties, // Create a custom filter with taps as our coefficients, // Generate an N320/N321 multi_usrp object. Below is the subdev mapping of RF Ports. The USRP E320 requires UHD version 3.13.0.2 or later. Before doing any major work with a newly acquired USRP N300/N310, it is recommended to update the file system. Disable autoboot on USRP E320 (sets least significant bit to 0), regardless of whether currently enabled or disabled: Enable autoboot on USRP E320 (sets least significant bit to 1), regardless of whether currently enabled or disabled. Other product and company names listed are Instructions on downloading the latest filesystem image and writing it to the SD card are listed below. When updating the file system using Mender, the tool will overwrite the root file system partition that is not currently mounted (note: every SD card comes with two separate root file system partitions, only one is ever used at a single time). Once the boot process successfully completes, a login prompt like the following should appear: By default, the root user's password is left blank. Connect the USRP to a host computer using either a 10Gb SFP or Fiber cables to SFP Ports 0/1. However, it is certainly possible to compile UHD and MPM by hand, e.g., in order to modify and try out changes without having to build entire filesystems in between. For Ubuntu/Debian based operating systems it can be installed with apt such as: The default Baud Rate for the Serial Console is: 115200. When the power button status LED is in the . We perform a sample rate conversion to the master clock rate within the FPGA. When UHD is driving a pin, each one of the radios (up to four in the case of the N310) can drive the GPIO pin. The difference between the three "default" profiles is how the amplifier is used: Either it is always on, always off, or it is switched on and off to optimize linearity. In order to facilitate the higher bandwidth, UHD uses a technology called Data Plane Development Kit (DPDK). This will run you through the first steps relevant to getting your USRP N3XX series up and running. The nominal LO input level is +5 dBm. The Filter API also allows to set some 3 dB analog filters on the AD9371 through the set_tx_bandwidth and set_rx_bandwidth UHD functions. To set a password, run the command. This can be used to debug kernel or boot-loader issues more efficiently than when logged in via SSH. The exact device node depends on your operating system's driver and other USB devices that might be already connected.

Calling. Run. that provides reliability and fault-tolerance for deployment. This device simplifies control and management of a network of radios by introducing the unique capability to remotely perform tasks such as updating software, rebooting, factory resetting, self-testing, host PC/ARM debugging and . NOTE: When operating the SFP+ Port at 10 Gb speeds, it is important to set a MTU of 8000 and not a value of automatic. To obtain all the FPGA images for your installed version of UHD, run the following command on the host computer with internet access: There is two versions of the E320 FPGA images shipped with UHD: - 1G for 1 Gb rates on the SFP+ port (default image). If there are multiple N3x0 devices in a single UHD session, they will be initialized in parallel. The halfband decimators/interpolators are not configurable. This device simplifies control and management of a network of radios by introducing the unique capability to remotely perform tasks such as updating software, rebooting, factory resetting, self-testing, host PC/ARM debugging and monitoring system health. One-hot encoded pps_select to use the internally generated PPS with a 10 MHz ref_clk. When updating the file system using Mender, the tool will overwrite the root file system partition that is not currently mounted. Any data stored on that partition will be permanently lost. For example, if the sticker says "P/N: 141064A-01L", it is a revision A module. Other product and company names listed are trademarks or trade names of their respective companies. The support page on our website is located at https://www.ettus.com/support. The least significant bit when MCU_FLAGS[0] is viewed as a binary value controls the autoboot. For more information on updating the FPGA image, refer to the UHD Manual at http://uhd.ettus.com . The command 'help' will list all available commands. This partition usually does not require touching. Your computer may need to be restarted for the MTU value to take effect. 5. You can run a simple test of the N3xx USRP by connecting an antenna and observing the spectrum of a commercial FM radio station in real-time, following the steps below: 1. The USRP E320 systemd network configuration files are located either at: /etc/systemd/network/, or for newer versions of the file system: /data/network/. The constraint files should not be modified. The USRP N320/N321 requires UHD version 3.14.0.0 or later. After updating that partition, it will reboot into the newly updated partition. After the device has obtained an IP address, you can remotely log into it from a Linux or macOS system with SSH, as shown below: NOTE: The IP address may vary depending on your network setup. To obtain the default micro SD card image for a specific version of UHD, install that version of UHD (3.11.0.1 or later) on a host system with Internet access and run: The image will be downloaded to /share/uhd/images/usrp_n3xx_fs.sdimg, where is the UHD installation directory. Every E320 series device connected to USB will by default show up as four different devices. NOTE: This USRP product is a piece of test equipment. In order to use your Universal Software Radio Peripheral (USRP), you must have the software tools correctly installed and configured on your host computer. You can quickly verify the operation of your USRP E320 by running the rx_ascii_art_dft UHD example program. This example will test one full-duplex stream using "RFA/A:0", at a rate of 61.44 MS/s, for 60 seconds: This example will test two full-duplex stream, at a rate of 30.72 MS/s, for 60 seconds: To avoid damaging the file system and causing any corruption, do not turn the device off with the power button without first shutting down the system. One-hot encoded pps_select to use the PPS from the GPSDO input to the FPGA. The protocols supported on the SFP+ and QSFP+ ports depend on the FPGA image currently loaded. Insert the updated micro SD card and power on the device. Sample rates as delivered to/from the host computer for USRP devices are constrained to follow several important rules. Any data you would like to preserve through Mender updates should be saved to the "data" partition, which is mounted at /data. The USRP N3xx systemd network configuration files are located at: /data/network/, or for older versions of the file system: /etc/systemd/network/. 1. To connect to the microcontroller, use the other UART device. The SD card is partitioned into four partitions: Note: It is possible to access the currently inactive root file system by mounting it. If the decimation or interpolation factor exceeds 256, then it must be evenly divisible by 4. In that case, add those permissions back before executing the .sh file: Executing the .sh file will prompt you for an installation path. Getting started guide; Related Products and Recommended Accessories. In that case, the pin can either track the ATR register of that radio channel, or it can be freely programmed. Press the Enter key when prompted for a password. Connect the SFP+ port on the device to an Ethernet port on the host computer using a 10 Gb SFP+ copper or fiber cable. Minimum version of UHD required: 3.14.0.0. When the source is set to "external", reading the LO frequency will return the ideal frequency for an external LO source. A common reason to update the FPGA image is in the case of a UHD/FPGA compat number mismatch (for example, if UHD has been updated, and now expects a newer version of the FPGA than is on the device). XG, WG), modify the device argument fpga= to a value of fpga=XG or fpga=WG. To use the LO located on the daughterboard in slot A, set LO export enabled to true. Proceed to the next section Verifying Device Operation. Use this . By using matched length cabling with N321s, up to 16 modules can use both of their RX and TX channels while sharing a single N321's LO signal, resulting in a 32 by 32 channel single shared LO configuration. usrp->set_tx_iq_balance(my_tx_iq_offset_value, 0); usrp->set_tx_dc_offset(my_tx_dc_offset_value, 0); usrp->set_tx_iq_balance(my_rx_iq_offset_value, 0); // This line will now set the gain for RF3 to 20.0: "type=n3xx,clock_source=external,time_source=external", "type=n3xx,clock_source=internal,time_source=sfp0". Users can host their own local Mender server, or use servers hosted by Mender as a paid service; contact Mender for more information. The first step in that process is to obtain an image. If you do not have screen installed, it can be installed via your package manager. Please see the separate application note, Writing the USRP File System Disk Image to a SD Card, for step-by-step instructions on writing the file system image to the microSD card. Please see the separate application note, Writing the USRP File System Disk Image to a SD Card, for step-by-step instructions on writing the file system image to the SD card. The hardware power on state and UHD initial state for the front-panel GPIOs is high-Z. Like with the serial console, you should be presented with a prompt like the following: The RJ45 port (eth0) comes up with a default configuration of DHCP, that will request a network address from your DHCP server (if available on your network). SDKs are distributed along with other binaries. Use this command to cleanly and properly shut the system down: The USRP E320 can be configured to power on and boot automatically when power is applied.
