IBC 2008: Rohde & Schwarz enhances broadcasting efficiency
Meudon-la-Forêt, le 16 juillet 2008 - "Driving Efficiency" is the motto under which Rohde & Schwarz will present its innovations at the International Broadcasting Convention. As an innovation for broadcasting T&M, the R&S ETH will be showcased for the first time. This portable instrument offers TV and spectrum analysis for mobile applications. In addition, Rohde & Schwarz scores with its transmitters due to their innovative energy concept that increases efficiency by up to 20 percent and reduces operating costs. This concept has already been implemented in the R&S NX8600 and R&S NX8300 high-power and medium-power transmitters. As a new highlight for DAB and T-DMB, the R&S NA8200 family of high-power transmitters boasts an energy-efficient system design and the new R&S SX801 DAB exciter.

The company's product portfolio supports the world's most common digital broadcasting standards, including ATSC, DVB-T/-H, DTMB, MediaFLO™, T DMB, DAB, ISDB-T and also its recent Brazilian version ISDB-TB. Furthermore, Rohde & Schwarz now offers the first options for the DVB-SH satellite-to-mobile standard and the Chinese CMMB mobile TV standard for broadcasting T&M equipment.

The R&S ETH handheld TV analyzer for DVB-T/H will be premiered at the IBC. The analyzer is a portable solution for indoor coverage measurements as well as for the installation and maintenance of low-power transmitters. It is therefore ideal for TV net-work operators that broadcast in DVB-T and for providers that operate a mobile TV network using DVB-H. The handheld analyzer's high-contrast color display and its capability to run up to 4.5 hours on battery power make it ideal for outdoor use.

The R&S Nx8600 high-power transmitters and the R&S Nx8300 medium-power transmitters feature an innovative energy concept. The core of this innovation is new amplifier technology. The amplifier characteristic can be selected to yield high efficiency even if the transmitter is operated at reduced power. The cooling system has also been optimized. All these features make it possible to reduce the energy consumption by as much as 15 percent, particularly of the medium-power transmitters. This benefits not only the environment, but also transmitter network operators and program providers since operating costs decrease.

Another new asset in the Rohde & Schwarz transmitter portfolio is the R&S NA8200 family of DAB transmitters. These transmitters are suitable for VHF band III and output DAB and T-DMB signals in the high-power range. Their output power is higher and their footprint lower than that of the existing DAB transmitters of the R&S NA6000 series. The R&S NA8200 family is also equipped with a function for optimizing efficiency at reduced output power. It furthermore comprises the new R&S SX801 DAB exciter. All important transmitter components are redundant in design. The
R&S NA8200 transmitters are air-cooled via internal fans. Remote control interfaces and a color display pro-vide operating convenience. If required, the R&S NA8200 transmitters can be easily upgraded to the R&S NW8200 TV transmitters, e.g. for DVB-H or MediaFLO™.
