Enhanced R&S ETL TV analyzer for ATSC Mobile DTV

Rohde & Schwarz is enhancing its R&S ETL TV analyzer with a set of comprehensive functions developed for ATSC Mobile DTV (ATSC MDTV). Rohde & Schwarz says these new capabilities make the R&S ETL the first analyzer that can perform all required measurements for installing, commissioning and maintaining ATSC MDTV networks using a single instrument. TV analyzer is suggested as an ideal solution for optimizing ATSC MDTV single-frequency networks (SFNs). Users will profit from its patented time-saving measurement method.

For TV coverage measurements in the field, Rohde & Schwarz also offers the R&S BCDRIVE software. Data measured at a number of stations can be analyzed in detail and displayed in straightforward fashion using the software.

ATSC MDTV networks can also be set up as single-frequency networks. SFNs provide more stable broadcasting reception, since all transmitters in a network broadcast signals on only one frequency. Better coverage of the broadcast area is achieved with multiple powerful transmitters, each operating on a different frequency. To optimize SFNs, Rohde & Schwarz has developed and patented a unique measurement method: The R&S ETL equipped with the R&S ETL-K321 software option allows users to precisely determine the frequency offsets of all transmitters in a network with a single measurement.
