<h2>Diversity of USRPs from NI and Ettus Research</h2>
<p> The compact low-cost B200 / B210 and NI 2900/2901 based on the RFIC AD9364 / AD9361 are USB-controlled and do not require a separate power supply.</p>
<p><img class="img-responsive" src="http://www.olnio.com/uploads/service/c8a950eb0d000fe3536dd555af4f5486.jpeg" alt="" width="300" height="218" /></p>
<p> The standalone USRP-2974 with Xilinx Kintex-7 and Intel Core-i7 running NI Linux RT enable UE prototyping for new communications networks and other tasks that require a combination of autonomy and mobility. </p>
<p><img class="img-responsive" src="http://www.olnio.com/uploads/service/48e19c96b5147691f3e384048d9cda6e.jpeg" alt="" width="300" height="160" /></p>
<p> Standalone N3xx with Xilinx Zynq and 10 Gigabit Ethernet are designed to create autonomous and distributed systems, including those with synchronization from GPS or White Rabbit.</p>
<p> The USRP-294x / 295x series models form the backbone of most multi-channel systems. In these models, the X310 motherboard provides Kintex-7 FPGAs and connectivity to the host computer via PCI Express and 10 Gigabit Ethernet, and the radio cards determine the radio path capabilities, device bandwidth and channel, phase synchronization capabilities using LO Sharing.</p>
<p> </p>
<h2>USRP-294x / 5x Series Appliances</h2>
<p> Most models contain two full duplex transceiver channels. Models USRP-2945/55 are 4-channel phase-locked receivers thanks to superheterodyne architecture and LO Sharing.</p>
<p><img class="img-responsive" src="http://www.olnio.com/uploads/service/e338aeffbca8a0dedea06b17f1ef1b7f.jpeg" alt="" width="494" height="307" /> <img class="img-responsive" src="http://www.olnio.com/uploads/service/ea4b2fac8fadd9ac40f1c4d49f536ee3.jpeg" alt="" width="572" height="356" /></p>
<p> The front panel of the USRP-294x / 5x series devices contains input-output lines: radio channel connectors and additional digital lines connected directly to the FPGA.</p>
<p><img class="img-responsive" src="http://www.olnio.com/uploads/service/395376e4c641e447fe1e749e25a43c4e.jpeg" alt="" width="860" height="362" /></p>
<p> The rear panel contains digital connectors for connecting to a PC or PXI via PCI Express and 10G / 1G Ethernet, as well as synchronization connectors: input and output of 10 MHz reference signals, trigger signals and PPS, GPS antenna connector.</p>
<p> On models supporting LO Sharing, the required connectors are also located on the rear panel.</p>
<p> </p>
<h2>USRP Synchronization with Octoclock-G CDA 2990</h2>
<p> An Octoclock block has been created to simplify USRP synchronization. It distributes 10 MHz and 1 PPS reference signals in star topology to 8 channels and also supports GPS referencing.</p>

<p> The ideology of NI for SDR is to develop a platform that allows you to solve problems from simple experiments to creating large-scale simulators of the interaction of hundreds of devices or precision testing systems for AFAR modules.</p>

<p> </p>
<p><span style="font-size: 14pt;">Recording and playback of wideband signals</span></p>
<p> The ability to record the entire signal, and then process or play it, simplifies many tasks. However, this imposes additional requirements.</p>
<p> So, already for signals with a bandwidth of 50 MHz over 4 channels, it is required to provide a bandwidth of 1 GB / s.</p>
<p> The NI platform provides tens of GB / s throughput throughout the signal path - in SDR devices, data bus, file storage, processor.</p>

<p>Broadcast antennas are installed based on several planning assumptions that never fully reflect reality. The network is being over-designed, and energy efficiency is decreasing. DVB-T amplifiers are inherently inefficient, exacerbating the problem.</p>
<p><span class="boldspan" style="font-weight: 400;">Challenge:</span> Optimize digital network performance by adapting real-time coverage based on user feedback using beamforming techniques</p>
<p><span class="boldspan" style="font-weight: 400;">Solution:</span> UE with an Internet connection will transmit the desired quality of service (QoS) metrics to a central controller. Based on this feedback data, broadcast powers and radiation patterns can be altered to optimize the energy efficiency of the broadcast network. This system is designed in such a way as not to require every user in any given area to be able to feed back to the data, limiting infrastructure overhead.</p>

<p> </p>
<p> Engineers working on the latest 5G Antenna-in-Module (AiM) and Antenna-in-a-Box (AiP) devices now have the advantage of reducing development time and meeting beamforming requirements with broader and more complex 5G NR signals. In addition, NI's faster test speed allows engineers to use denser spatial grids for finer resolution and dramatically improved measurement uncertainty. A test bench for prototyping and verification of microwave mm-range devices helps engineers create a very cost-effective and fast-response solution.</p>

<p>The mmWave test bench allows engineers to tune spatial sweeps using a thin (dense) 3D mesh and perform RF measurements of thousands of points in space using autonomous movement. That is, as soon as the sweep begins, the positioner and mmWave VST synchronize and operate independently using trigger signals, without having to rely on software commands from the controller. Since this approach avoids the more time-consuming, software-driven execution of "action -> stop -> measure ", the results will be available in no time.</p>
<p>Consequently, validation engineers improve the resolution of beamforming measurements while reducing test time. Using the mmWave OTA Validation benchmark, engineers can create, store, or distribute detailed parametric results.</p>

<p> The mmWave OTA test bench takes advantage of the newly released NI mmWave VST and the tightly synchronized PXI backplane to create a fast, affordable and ready-to-use OTA reference test system that engineers can tailor to their test needs. ... In addition, using other platform elements such as TestStand and LabVIEW, the mmWave Test Bench gives users the ability to customize their tests, create and store reports, and visualize their test results interactively.</p>

<p> The modular architecture of the NI mmWave VST allows it to scale to accommodate the diversity and complexity of 5G mmWave devices. Using the NI VST, engineers gain fast, laboratory-scale, wide-bandwidth IF and MW signal generation and analysis for OTA testing of 5G semiconductor devices.</p>
<p> For testing RF-to-RF devices, the mmWave OTA Validation Test reference architecture places mmWave VST radio heads with powerful bi-directional ports very close to the RF connectors on the outside of the anechoic chamber. Engineers can also use the VST IF ports to interface the IF-RF TC.</p>
<p> </p>

<p> </p>
<p><span class="boldspan" style="font-weight: 400;">RF Isolated Anechoic Chamber</span></p>
<p> Correctly characterizing the beamforming characteristics of AiP devices requires a controlled and quiet RF environment in an anechoic chamber with high quality radio-absorbing material that minimizes reflections. In addition, to ensure repeatability of measurements, the motion system must provide a high angular resolution and each time move to an exact point in space.</p>
<p> The test bench includes a carefully selected anechoic chamber with a 2-axis (azimuth and elevation) DUT positioner at the bottom and a fixed measurement antenna at the top. This camera includes a National Instruments real-time motion controller that enables NI to use a fast, continuous motion OTA test method.</p>
<p> The distance between the positioner and the DUT allows far-field testing of 5G MW AiP devices with an antenna aperture of 5 cm or less (in accordance with 3GPP specification 38.310 for category 1 DUTs).</p>

<p> The MMW Prototyping and Verification Test Bench includes test software that helps engineers quickly set up extensive spatial sweeps to characterize their device's antenna patterns while they manufacture, render, store, or distribute detailed parametric results. </p>
<p> </p>
<p> Users can use the mmWave test bench software as a complete test environment for OTA validation tests. Alternatively, users can incorporate some of its components into their existing test environment, or use individual components as stand-alone utilities.</p>
<p> </p>
<p> OTA testing needs can vary greatly for different applications and DUT types. To help engineers adapt to different test situations, mmWave OTA Validation Test Software offers a modular approach that is extensible for different user needs such as custom DUT control, special sweep configurations, signal routing, etc.</p>
<p> </p>
<p> Engineers working on both manual and automated verification tests of mmWave OTA devices will benefit from the following components built with LabVIEW and TestStand:</p>
<p> </p>
<ul>
<li>MmWave OTA Test Configuration User Interface: An open source LabVIEW graphical user interface (GUI) that helps users configure the test matrix to run, including measurement parameters, sweep parameters, and connection settings</li>
<li>TestStand Template Launch Sequences: The mmWave OTA Validation Test Software installs test sequence templates that engineers can use to launch the configuration files they create using the mmWave OTA configuration UI.</li>
<li>Soft front of the mmWave OTA Test Positioner: The mmWave OTA SFP test positioner allows users to operate the positioner interactively.</li>
<li>mmWave OTA Test Visualizer: OTA Test Visualizer mmWave completes offline setup and analysis of OTA test data for antenna measurements. Engineers can use the OTA Test Visualizer mmWave to invoke various visualizations of results and analyze measurements and antenna patterns.</li>
<li>OTA measurement interface: To simplify the process of storing measurement values, importing and exporting measurement data, and interpreting measurement results using automated sequences in TestStand.</li>
<li>System Calibration Utility: NI provides RF System Calibration Assistant, a free software utility that controls RF devices, including an external RF power meter, to perform system loss calibrations on all RF equipment components in the signal path (cables, adapters, antennas, etc.) t.D.) taking into account both horizontal and vertical polarization.</li>

<p><span style="font-family: Roboto, sans-serif;"><span style="font-size: 15px;">The channel emulator for software and hardware modeling of a variety of radio devices - the microwave supercomputer - is based on broadband SDR devices combined into a single system with an open FPGA for built-in processing of radio signals. If necessary, MAC and higher levels are implemented in multi-core CPUs. For the calculations of complex 3D scenarios, powerful video cards are used, which allows you to generate the necessary parameters on the fly and do without the preparation of large amounts of IQ data and post-processing. To calculate the interaction of radio signals in real time, clusters of powerful FPGAs based on Xilinx Virtex, interconnected by multi-gigabit lines, are used. Server controllers and fiber optic network ensure minimal delays between computers and transceiver modules. This design provides full-size real-time emulation of simulated and connected devices. At the same time, the modularity and compactness of the emulator is preserved within the standard 19 ”racks.</span></span></p>
