Transposers from Rohde & Schwarz Deliver Seamless Coverage in Digital and Analog Broadcasting Networks
Munich, May 16, 2008 - Rohde & Schwarz is adding the R&S XLx8000 transposer family to its product portfolio in the UHF/VHF low-power range. Together with the R&S SLx8000 low-power transmitters, the transposers provide a highly flexible solution for filling coverage gaps. The equipment's extremely high level of integration provides a very favorable price/performance ratio. Options are available to convert the transposer into a gap filler. The R&S XLx8000 supports the ATSC, MediaFLO(TM), DVB-T/-H, DAB/T-DMB and DTMB standards as well as analog TV standards.
The R&S XLx8000 transposers make it possible to easily fill coverage gaps or expand transmission areas. When used as gap fillers in single-frequency networks, signals can be efficiently amplified without occupying additional frequency resources. Rohde & Schwarz offers two options to convert the transposer into a gap filler. Depending on the desired transmission power and environmental variables, the very favorably priced software option for echo cancellation usually suffices. Enhanced echo cancellation, which increases the performance of the software algorithm by means of additional hardware, is recommended for high power applications and extreme conditions.
The transposers for the UHF and VHF frequency ranges cover power ranges up to 150 W ATSC, 250 W ATV, 100 W DVB-T/-H or 300 W DAB. Their compact design requires little space: two height units for up to 15 W ATSC power, three height units for up to 150 W ATSC power and four height units for 300 W DAB power. The space-saving concept can be beneficial especially for small transmitter stations with limited space.
The following options are available: an integrated GPS module, an internal DVB T/-H monitoring receiver, as well as an SNMP agent or parallel interface as remote control interface. Local operation can be performed using either a display and keyboard, or with a computer and conventional web browser, which is also suitable for remote control. The operation-relevant data of the R&S XLx8000 is stored in the unit on a compact flash memory card that is directly transferred from one transmitter to the next if servicing is required. The transposers support the N+1 (including 1+1) standby configuration.
The R&S XLx8000 transposers/gap fillers from Rohde & Schwarz will be available as of the second quarter of 2008.
