The compact design of the R&S SCx8000 is the direct result of reducing the number of required rack components to a minimum. This is achieved by implementing a module-based air-cooling concept that avoids a central rack cooling system, as well as by integrating an RF splitter and combiner solution in the amplifier modules. New redundancy concepts for the exciter and amplifier further minimize space requirements and enhance availability. The transmitter can be switched from analog to digital transmission at any time either by remote control or manually. This flexibility is a crucial advantage, especially in transitional phases. The power output stage of the R&S SCx8000 comes equipped with a broadband precorrection for the customer's preferred digital standard, the so-called set & go feature. This eliminates the need for manual precorrection on site and allows the transmitter to be put into operation faster. The R&S SCx8000 series uses the new R&S Sx801 exciter, which can be controlled and monitored via its display. The transmitters for the UHF range feature output power of up to 450 W (ATSC/ATSC Mobile DTV) or 300 W (DVB-T, MediaFLO) with one amplifier. If a second amplifier with an integrated combiner is used, up to 900 W (ATSC/ATSC Mobile DTV) or 600 W (DVB-T, MediaFLO) can be reached.

digiGO! — TV Transmitter Ties Into Low- To Medium-Power Market
Rohde & Schwarz is setting a new standard for performance with its R&S SCx8000, a compact and efficient TV transmitter for the low- to medium-power market segment.
Although specifically developed for digital TV standards such as ATSC, ATSC Mobile DTV, DVB-T, DVB-H and MediaFLO, the R&S SCx8000 also performs flawlessly for analog TV. In addition to offering an excellent price/performance ratio and new redundancy concepts for this power class, its large-scale integration (LSI) design reduces infrastructure, leasing, and installation costs, and its high efficiency saves energy. This combination of features makes it easier and more economical for broadcasting and mobile radio network operators to set up or expand their networks.
