Key facts
The R&S®THV9evo VHF high-power transmitter family for DTV and DAB+ is the next step in reducing terrestrial broadcast operating costs.
The overall energy efficiency of up to 46 % for COFDM and 50 % for ATSC is some of the best ever. The R&S®THV9evo maintains the tried-and-tested strengths of the R&S®THU9/R&S®THV9 platform. Network operators benefit from low operating costs throughout the product lifecycle.
R&S®THV9evo transmitters are up to 50 % energy efficient (including the cooling system), setting a benchmark in their class. Years of experience and continual improvements have let Rohde & Schwarz completely master Doherty technology.
R&S®THV9evo transmitter systems have a maximum power density that accommodates multiple transmitters in a single rack and significantly reduces their footprint relative to conventional transmitters, substantially reducing the space required and site rental costs.
Thousands of R&S®THU9/R&S®THV9 transmitters are used around the world. Every day, they prove their reliability. The Rohde & Schwarz high-power transmitter platform meets network operators needs by minimizing operation costs while maintaining maximum availability.
The power supplies and first-stage combiners in R&S®THV9evo amplifiers are liquid cooled to maximize their lifetime and reliability, while minimizing the amount heat dissipated into operating rooms and lowering air-conditioning costs.
Intelligent optimization maximizes efficiency in changing environments, both adaptively or at the press of a button. When changing channels or adjusting transmitter power, efficiency optimization keeps energy costs to a minimum at all times.
In contrast to conventional couplers, the R&S®THV9evo low-loss power combiner is directly connected to the amplifiers and comes with integrated coolant distribution. Fewer RF interconnections and no cooling hoses ensure maximum efficiency and reliability.
The Rohde & Schwarz exciter uses a purely software based approach to prepare network operators for ATSC 3.0. A high-performance server helps network operators leverage the full system capabilities and flexibly respond to future signal processing requirements.
Integrated signal analysis offers instant feedback on signal quality combined with self monitoring for unique quality of service.
