    Demystifying 5G - Testing a 5G IF transceiver

    Published on Jun 4, 2018

    The video explains the benefits of direct RF sampling for 5G systems. It demonstrates how to test a discrete transceiver for 5G NR based on the latest data converters from Texas Instruments, the DAC38RF82 and the ADC12DJ3200, using the R&S®SMA100B RF and microwave analog signal generator, the R&S®SMW200A vector signal generator and the R&S®FSW signal and spectrum analyzer from Rohde & Schwarz.

    The demystifying 5G video series discusses main topics related to 5G including requirements, timeline, frequency bands and waveforms.

    Demystifying 5G - Over the air (OTA) testing for 5G NR in far-field and near-field

    Published on Jul 4, 2018

    This video answers common questions that arise with 5G over the air testing. Where does the far-field start? Is the Fraunhofer distance “the” far-field distance? Do I need to know the antenna location inside the device under test? How can I measure under far-field conditions at near-field distances and remarkably reduce the test setup size?

    Demystifying 5G – Creating far-field conditions at short distances for 5G over the air testing

    Published on Jul 6, 2018

    Over-the-air (OTA) testing for 5G NR devices usually results in high measurement distances – particularly for mmWave frequencies and massive MIMO devices. The video discusses various solutions to significantly reduce the measurement distances in order to achieve a compact test setup for mobile device and base station OTA testing. Learn more about software- and hardware-based field transformations for TX and RX OTA measurements as well as important quiet zone parameters and achievable performance.

    Demystifying 5G - 5G NR network measurements at 3.5 GHz

    Published on Dec 3, 2018

    The video demonstrates how to perform 5G NR network measurements at 3.5 GHz. In the example shown, the R&S®SMW200A vector signal generator generates a 5G NR signal. The captured RF measurements are visualized with the R&S®ROMES4 drive test software that supports real-time network analysis, optimization and troubleshooting. R&S®ROMES4 is highly configurability allowing to customize the views according to the user’s needs.
