KG"></A> <p>With TV Transmitter Family <a href="http://www.rohde-schwarz.com/product/nv7000.html">R&S NH/NV7000</a>, Rohde & Schwarz has developed a new generation of liquid-cooled UHF transmitters for analog and digital TV. They consist of the following main components: <ul> <li>Exciter </li> <li>Power amplifiers incl. power supply </li> <li>Transmitter rack</li> </ul></p> <p>The UHF transmitter family R&S NH/NV7000 is available for analog TV with powers of 2 kW to >40 kW and for DVB-T with powers of 400 W to >5 kW. Each amplifier has its own power supply which is integrated into the amplifier module and thus cooled by the liquid cooling system. <br> The amplifier module is self-engaging and can be exchanged during operation without any liquid loss of the closed cooling system and without impairing the operation of the other modules. <br> The power supplies are fed with AC supply voltage, ie no auxiliary voltage supplies are required, which improves the availability of the transmitters. Parts exclusively made of stainless steel, aluminium or plastic are used for the cooling system in the transmitter rack.</p> <p>All transmitters can be equipped with a second exciter and the associated automatic switchover unit, the two units being integrated into the transmitter rack.</p> <p>The TV Transmitter Family R&S NH/NV7000 features a frequency range from 470 MHz to 860 MHz, an advanced LDMOS technology for power amplifiers, digital precorrection, liquid-cooled, high redundancy, highly compact for minimum space requirements, cost-effective installation and all possible standby concepts (single transmitter, active or passive output-stage standby, exciter standby). </p> <p>The transmitters with a maximum output power of 10 kW for analog TV, 3.4 kW for DVB-T or 4.1 kW for ATSC are accommodated in a rack 630 mm in width. This means space requirements are at a minimum since also components such as the harmonics filter, the vision/sound diplexer and the colour subcarrier trap for analog TV are accommodated in the transmitter rack.</p> <BR clear="ALL"> <P> ROHDE & SCHWARZ GmbH & Co.
