  • RF amplifiers from Rohde & Schwarz in accelerator physics

    Particle acceleration requires cavity resonators that are driven with high RF powers at defined frequencies. Rohde & Schwarz offers RF solid-state amplifiers for frequencies ranging from 9 kHz to 6 GHz, delivering CW power up to 80 kW.

  • UHD 4K end-to-end broadcasting over DVB-T2

    In this application note, a UHD 4K end-to-end solution utilizing products from Rohde & Schwarz is described in detail from the point at which 4K content is captured until its delivery to households via a DVB-T2 SFN network.

  • Quality Measurements on Digital and Analog TV Transmitters - Using the R&S ETL

    All types of information transmission, including the 'one-way' transmission used in broadcasting, involve feeding a radio frequency (RF) signal to an antenna. This is the essence of the most basic type of transmitter used to emit electromagnetic waves. In the real world, however, a transmitter used for broadcast applications, for example, is much more complex in terms of its functions and design. The different transmitter components must be carefully coordinated. There are many quality parameters that are critical in ensuring that a proper output signal is delivered. Rohde & Schwarz designed the R&S® ETL TV analyzer especially for broadcasting applications. The analyzer allows the measurement of the quality parameters that are relevant in analog and digital broadcasting. This Application Note describes the typical quality measurements performed during compliance testing of TV transmitters. The approach discussed here is based on the example of Rohde & Schwarz terrestrial transmitters for analog TV and DVB-T/H.

  • Malware Protection

    Rohde & Schwarz recognizes the potential risk of computer virus infection when connecting Windows®-based test instrumentation to other computers via local area networks (LANs), or using removable storage devices. This white paper introduces measures to minimize malware threats and discusses ways to mitigate risks while insuring that instrument performance is not compromised. The paper discusses the use of anti-virus software, with recommended configuration settings. It also outlines how to keep the Windows® XP operating system properly updated through regular installation of OS patches.
