Switching can be a cost-effective and efficient option for expanding the channel count of your instrumentation, but it is not always the best option. Learn about the four different switching architectures and determine the best strategy to meet the needs of your test system.
The wireless communication infrastructure must evolve to support growing user and data demands. See how service operators are investigating the use of mmWave technology to evaluate the best candidate frequencies for use in next gen 5G mobile applications.
National Instruments (NI) announced a baseband model of the second-generation vector signal transceiver (VST). The PXIe-5820 module is the industry’s first baseband VST with 1 GHz of complex I/Q bandwidth and is designed to address the most challenging RF front-end module and transceiver test applications, such as envelope tracking, digital predistortion and 5G test.
In a perfect world, systems would never fail. Unfortunately, this is not reality—at least not yet. Systems fail and sudden, unexpected failures can be costly. Although you cannot completely remove the risk of failure, even with the most well-thought-out plans, you can reduce it. Ensure you have a maintenance strategy that can help you manage cost if something does go wrong and reduce the risk of failure.
NI announced the WLAN Test Toolkit 17.0 with support for Draft 1.1 of the IEEE 802.11ax standard. Combined with NI’s second-generation Vector Signal Transceiver (VST), the WLAN Test Toolkit 17.0 supports 802.11ax waveform generation and analysis for characterization, validation and production test of products, such as RF front end components, wireless modules and user devices, that implement Draft 1.1 of the IEEE 802.11ax standard.
To address our rapidly approaching, hyper-connected future and the unprecedented demand on current 4G wireless networks, researchers at the University of Bristol and Lund University set out to test the feasibility of massive MIMO as a viable technology for 5G networks. Using the NI MIMO Prototyping System, the team was able to rapidly test new ideas on their way to implementing the world’s first live demonstration of a 128-antenna, real-time massive MIMO testbed and set two consecutive world records in spectral efficiency.
With the modern mobile device revolution, semiconductor suppliers are challenged to increase capability, integration, and performance while reducing time to market. Test needs a new approach based on an open, flexible platform at significantly lower cost. NI is bridging this gap by building on the stability and capability of the PXI platform to deliver off-the-shelf modular technology to both the characterization and production engineer.
Today, at the IEEE Wireless Communications and Networking Conference (WCNC) in San Francisco, National Instruments (NI) publicly demonstrated a real-time, over-the-air prototype aligned with the Verizon 5G specification. The 28 GHz system uses OFDM with eight component carriers in a 2x2 downlink MU-MIMO configuration, with hybrid beamforming and a self-contained subframe, yielding a 5 Gbps peak throughput that is scalable to over 20 Gbps with eight MIMO streams.
The power amplifier (PA) – as either a discrete component or part of an integrated front end module (FEM) – is one of the most integral RF integrated circuits (RFICs) in the modern radio. Download this white paper to learn the basics of testing RF PAs and FEMs via an interactive white paper with multiple how-to videos.
