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 Ω 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.
