Rohde & Schwarz unveils TV transposer/gap filler

Rohde & Schwarz has unveiled the new R&S XV7002 TV transposer/gap filler for efficient operation of digital TV transmitter networks in DVB-T systems.

TV signals from a master transmitter can be rebroadcast directly so that small gaps in the network can be filled easily. Network operators can also use the TV transposer/gap filler for the regional expansion of networks where the installation of additional transmitters would be too expensive.

The new TV transposer/gap filler enhances the variation capabilities of the digital transmitter network, which enables more detailed and cost-oriented planning. The R&S XV7002 makes use of the amplifier modules and the modern control concept of the Rohde & Schwarz R&S SV7002 low-power transmitter series. It provides an identically high degree of flexibility for the installation and maintenance of transmitter networks.

The TV transposer/gap filler rebroadcasts off-air signals directly from the master transmitter, without requiring complex signal feed and modulation. The network coverage of digital transmission equipment can therefore be expanded quickly, easily and above all according to requirements. The R&S XV7002 operates as a gap filler in a single-frequency network (SFN) or as a TV transposer in the UHF band. A received VHF or UHF channel is rebroadcast in a UHF channel. Double IF conversion ensures high adjacent-channel isolation and permits fast frequency changes in the UHF band without any need for filter tuning.

The new TV transposer/gap filler R&S XV7002 is now available. For more information, please visit: www.rohde-schwarz.com.
