Rohde & Schwarz enhances TV analyzer with MPEG-2 analysis
Munich, Apr 30, 2008 - The R&S ETL TV analyzer from Rohde & Schwarz now includes features and options for MPEG-2 transport streams. The instrument combines the functions of an RF TV analyzer, an MPEG-2 analyzer and a spectrum analyzer, transforming it into a universal test platform. This enables network operators to perform all required measurements on TV transmitters as well as cable headends – both when setting up systems and placing them into operation as well as when performing service or maintenance. In the production of TV transmitters or modulators, the R&S ETL is the ideal solution for quality assurance. It supports ATSC, DVB-T/-H, DTMB, DAB and DVB-C as well as the most common analog TV standards.
The R&S ETL can also be used for coverage measurements in the field in order to optimize transmissions. The analysis functions have a level of detail that could previously be achieved only by using separate professional instruments. Rather than three instruments, the user now needs only the compact R&S ETL. Since all measurements run on a single platform, time-consuming switchovers between separate test instruments are eliminated.
The graphical user interface is easy to use and several features have been included to speed operation. For example, users do not have to re-enter the frequency or channel bandwidth for each measurement. The R&S ETL offers a comprehensive overview of all relevant operating parameters. Measurement results are immediately output on the display, thus permitting direct comparison of the data. The source of errors can be quickly and fully pinpointed and documented.
The R&S ETL can handle detailed MPEG-2 analysis. It provides data about the composition of the transport stream, reveals information about the contents of the individual MPEG tables and determines the bit rates of programs and data contents. A highlight is the optional MPEG-2/H.264/MPEG-4 decoder. It can output the measured TV signal on the integrated display of the R&S ETL even if the signal itself is encoded in high definition (HD) format. This gives the user detailed, complete information about the quality of the transmitted signal.
For MPEG-2 analysis with the R&S ETL, the following options are available: the R&S ETL-B280 MPEG processing board, the R&S ETL-K282 MPEG analysis/ monitoring option, the R&S ETL-K283 in-depth analysis option, the
R&S ETL-K285 option with transport-stream template monitoring functionality as well as the R&S ETL-B281 video and audio hardware decoder.
The options are now available from Rohde & Schwarz.
