Original Press Release:
Now Available for the VHF Band: Maximum Efficiency with R&S SCx8000 Compact Transmitters from Rohde & Schwarz
Munich, - Rohde & Schwarz is extending its R&S SCx8000 family of transmitters with two models for the VHF band, the R&S SCA8000 and the R&S SCW8000. This family, whose transmitters are the most compact and efficient in their class, now includes models in the 200 W to 600 W power range for digital television (DTV) and DAB and in the 350 W to 1100 W power range for analog television (ATV). The R&S SCW8000 supports both analog and digital TV standards such as ATSC Mobile DTV, DVB-T, DVB-H and MediaFLO(TM), and is DVB-T2-ready. The R&S SCA8000 supports the DAB, DAB+ and T-DMB audio broadcasting standards.
The R&S SCx8000 broadcasts DTV and DAB with an output power of up to 600 W and is only 4 HU high, making it the most compact transmitter in its class in the VHF band. Its compact size is due in large part to its LSI design and innovative exciter and amplifier redundancy concept. Up to six 600 W transmitters can be installed in a single rack, enabling network operators to significantly lower their infrastructure, site lease and installation costs. With its high efficiency of up to 24 percent in the VHF band, the R&S SCx8000 also reduces power consumption and electricity costs.
The transmitter's power output stages have a set-and-go feature that provides broadband precorrection for each digital standard. This eliminates the need for manual, on-site precorrection and allows the transmitter to be deployed quickly. In addition, the transmitter can be switched from analog to digital television with the push of a button and without the need for hardware changes - a feature that affords users a high level of investment protection.
The amplifiers, with an output power of up to 400 W for DTV and DAB and 700 W for ATV, come with two power supplies as standard. Optionally, a third power supply can be added to provide 2+1 redundancy. In the event that one of the two power supplies fails, transmission continues uninterrupted, without loss of power. Using only two exciters, the innovative, space-saving exciter redundancy concept guards against broadcast outages. A central control unit is not required. The control exciter acts as the transmitter control unit, the program exciter as the RF source. If the program exciter fails, the control exciter takes over RF signal generation. If the control exciter fails, the program exciter continues transmitting using the known parameters.
The VHF R&S SCA8000 for digital audio broadcasting and R&S SCW8000 for analog or digital television are now available from Rohde & Schwarz.
