Measurements of very high noise figure components are performed for a number of reasons. For instance, in a wide range of applications, devices under test (DUT) are characterized within a complex test setup that includes high losses before or after the low noise DUT.
Read this white paper to learn more on over-the-air (OTA) testing on 5G NR devices. Focusing on RF conformance aspects and UEs, the paper examines the requirements described in the technical specifications. You will learn about antenna measurement key parameters, test methods and setups, and 3GPP OTA testing for UEs.
Rohde & Schwarz has developed the R&S SMM100A vector signal generator and the R&S FSVA3000 signal and spectrum analyzer to meet the driving demand for test equipment due to the exponential growth of 5G adoption and the trend toward high frequency, wide bandwidth networks.
IEEE 802.11ax is intended to improve the user experience and network performance in dense deployments in the unlicensed bands. Explore the technology and get an overview of receiver and transmitter test requirement. Learn about the main goals and features of IEEE 802.11ax, the high efficiency PHY, and test requirements.
With advances in digital signal processing techniques modern wireless communications systems and radar systems have become increasingly digital and more constraints have been placed on packing more information into less and less bandwidth. On the wireless side, modulation formats have become more complicated with less margin for symbol error.
This white paper examines everything from lab-based testing and in-field performance testing to over-the-air (OTA) testing needs for vehicles. In the end, a clear overview of supplementary, non-communication related testing aspects in the automotive world is offered.
