R&S®NH8600 UHF Transmitter Family
Liquid-cooled high-power transmitters for analog TV
The R&S®NH/NV8600 transmitter family represents a new generation of liquid-cooled UHF transmitters for analog TV. The transmitters include the following main components:
- Exciter
- Power amplifier incl. power supply
- Transmitter rack
The UHF transmitters are available for analog TV with powers from 3.5 kW to 30 kW. Each amplifier has its own power supply unit that is integrated in the amplifier module and thus cooled by the liquid cooling system.
The amplifier power supply units are fed directly by the AC supply voltage, additionally increasing the availability of the transmitters. Parts exclusively made of stainless steel, aluminium or plastic are used for the cooling system in the transmitter rack. The amplifier module is self-engaging and can be exchanged during operation, without liquid escaping from the closed cooling system and without impairing the operation of the other modules. A second exciter (standby) and an automatic switchover unit can be integrated into all transmitters.
