Rohde & Schwarz presented an optimized UHF/VHF transmitter platform for the low-power range at IBC2007.

The platform consists of the R&S SLx8000 transmitter family and the associated R&S XLx8000 transposers and gap fillers, which make it possible to flexibly close smaller coverage gaps.

R&S SLx8000 transmitters support the DAB/T DMB, DVB-T/-H, and ATSC standards as well as virtually all analog TV standards. The R&S XLx transposers and gap fillers can also handle the MediaFLOTM and DTMB standards.

The transmitters for the UHF and VHF frequency ranges cover the power ranges up to 100 W DVB-T/-H, 160 W ATSC, 250 W ATV, and 300 W DAB.

Options include an integrated GPS module, an internal DVB-T receiver for retransmitter or monitoring applications, and an SNMP agent or parallel interface as remote control interface. A digital algorithm will soon be available for the gap filler for suppressing echoes. This algorithm will allow operation in single-frequency networks.
