The universal multistandard platform for the analysis of TV and mobile TV signals

The R&S®ETL TV Analyzer from Rohde & Schwarz is a completely new, universal multistandard platform for the analysis of TV signals. It combines TV test receiver and spectrum analyzer functionality in a single unit while providing high measurement accuracy. An innovative instrument concept allows new TV standards to be implemented on a software and hardware basis. Both digital (e.g. DVB-T/H) and analog TV standards can thus be integrated in a single instrument. The R&S®ETL TV Analyzer uses realtime demodulation throughout.

  • Multistandard-compatible
  • Software- and chip-based demodulators
  • All demodulators operating in realtime
  • analysis of TV and mobile TV signals
  • Wide range of TV signal analysis functions
  • Integrated spectrum analysis functions
  • MPEG-2 analysis and monitoring (optional)
  • Instrument design optimal for portable and stationary use
  • Capable of handling analog TV standards as well as DVB-T/H, ATSC/8VSB, DTMB (China) and DVB-C (J.83/A/C) digital standards

Demodulation in realtime

The software- as well as the hardware-based demodulators are designed for realtime operation throughout. This makes the R&S®ETL the only TV analyzer in its class that performs BER measurements and complete analysis consistently in realtime. The use of realtime demodulators has the additional advantage that demodulated analog video and audio signals as well as digital MPEG transport streams are available for further processing.

Wide frequency range

With a frequency range from 500 kHz to 3 GHz, the R&S®ETL covers not only the conventional broadcast frequencies but also the frequencies in the L and S bands, which are steadily gaining in importance. The TV analyzer‘s range of applications is thus considerably expanded.

Versatile measurements for ATV and DTV

The R&S®ETL offers a wide range of functions for measurements on digital TV signals. In particular, the constellation diagrams are displayed in very fine detail and build up at very high speed. As an alternative to the constellation diagram, the results of signal parameter measurements can be displayed together with the results of signal analysis in clear-cut tables. In the analog domain, the R&S®ETL offers as standard an extensive range of functions for measurements on vision and sound carriers. A video scope function, which is likewise provided as standard, enables further analysis in user-selectable video lines.

Measurements such as C/N, CSO, and CTB have been implemented especially for CATV applications. The R&S®ETL can optionally be equipped with a preselector including an additional 75 O input.

The wide variety of TV-specific measurements provided by the R&S®ETL is complemented by measurements in the spectrum. Spectrum measurements such as shoulder distance in accordance with ETSI TR 101 290, channel power, and adjacent-channel power can thus be performed using a single instrument.

Special functions such as frequency counter and noise and phase noise markers round out the range of functions and turn the R&S®ETL TV Analyzer into a real all-purpose instrument.

MPEG analysis and monitoring

In addition, the R&S®ETL may be equipped with MPEG options that provide detailed information about the MPEG-2 transport stream. Previously, this was possible only by using separate, highly specialized MPEG analyzers.

You thus have a powerful tool at hand for verifying the accuracy of content that is pending transmission.

The capability to send error messages over the integrated SNMP interface as soon as an error occurs in the transport stream expands the R&S®ETL's scope of applications to cover even long-term monitoring.

TV picture display

The quality of a TV picture often provides a very fast indication of the quality of the entire transmission path and its components. When equipped with the R&S®ETL-B280 und R&S®ETL-B281 options, the R&S®ETL can display TV pictures for analog TV as well as digital TV, thus increasing its already broad scope of analysis functions.
