O padrão de televisão digital DVB-T2 adquire cada vez mais importância devido à menor disponibilidade de frequências. No mundo inteiro, novos sistemas estão na fase de avaliação e muitos países já concluíram a implementação do padrâo DVB-T2. Os transmissores de radiodifusão estão sujeitos a normas particularmente exigentes no que se refere à qualidade de transmissão do sinal, porque até mesmo pequenas falhas podem levar a interrupções de serviço para muitos telespectadores e incluso perturbar os canais adjacentes.Um único instrumento, o analisador de TV R&S®ETL, executa todas as medições do transmissor DVB-T2 necessárias, do teste inicial de aceitação para o transmissor, até as medições executadas durante o comissionamento e manutenção preventiva.As medições descritas aqui satisfazem as especificações de teste de muitos países e clientes. Os usuários só precisam definir os valores limite corretamente.

A dedicated interactivity test enables low latency measurements and the calculation of an interactivity score that indicates the network’s readiness for specific use cases (e.g. cloud gaming, online meetings, AR/VR etc.). The machine learning-assisted software suite SmartAnalytics offers new features to get automated insights.
In addition, the emergence of private 5G networks for manufacturing, warehouses, ports, etc. brings forth new stakeholders with more demanding performance and quality requirements. With our wide interference hunting portfolio, R&S covers the needs of interference hunting specialists as well as field technicians occasionally searing for external interference sources.
This application note provides practical hints to accurately characterize and de-embed these lead-in and lead-out structures with R&S Vector Network Analyzers ZNA, ZNB, ZNBT and ZND.

LTE provides global mobility with a wide range of services that includes voice, data and video in a mobile environment with lower deployment costs. Mobile networks are rapidly transforming (traffic growth, increa-sed bit rates per user etc.) due to new technologies such as LTE. The growth in mobile traffic is mainly driven by devices such as smartphones and tablets. To get the best performance out of an LTE network, it needs to be optimized continuously. This white paper examines wireless network optimization challenges from a radio network perspective.

Rohde & Schwarz joins forces with Tsinghua University, Actenna Technology and others to conduct RIS technology trialsTo further exploit the huge potential of 5G, the wireless industry has continued to develop the standard up to Release 16, and development continues. But technology does not stand still, and even as 5G presses forward, a new generation of cellular technology is emerging. Cutting-edge 6G research is already underway at communications equipment manufacturers and research institutions, and reconfigurable intelligent surfaces (RIS) is a major area of interest in 6G research. Rohde & Schwarz, with Tsinghua University and Actenna Technology, recently completed an evaluation and trial of RIS technology to comprehensively evaluate the effects and performance of RIS deployment.

Rohde & Schwarz achieves breakthrough in sub-THz research with 140 GHz multi-channel transceiver characterizationRohde & Schwarz is advancing its pioneering sub-THz research in the D-Band and has reached important milestones. In collaboration with the Berkeley Wireless Research Center (BWRC), the test and measurement expert has successfully characterized a TX/RX multi-antenna chip (CHARM) operating at up to 140 GHz, using their D-Band over-the-air (OTA) test chamber. Academia and industry leaders agree that the 110 GHz to 170 GHz frequency range, known as D-Band, is critical for beyond 5G and 6G mobile communications and future automotive radar applications.
