R&S®XLx8000 UHF/VHF transposers offer compact, flexible solutions to reliably fill coverage gaps in transmitter networks. Plus, they are specially designed to meet the requirements of small, remote transmitter sites that are difficult to access, offer only limited space, and whose power supply may be subject to strong variations.

The R&S®XLx8000 family includes UHF and VHF transposers for digital and analog TV as well as for digital sound broadcasting. The compact devices can be used as transposers or retransmitters. Due to the short processing time, R&S®XLx8000 transposers can also be integrated into digital single-frequency networks (SFNs). Feedback is eliminated by high-quality, two-level echo cancellation. Intelligent operating functions reduce the transposers' setting times. For example, the automatic set&go function does away with a time-consuming manual precorrection of the output stages for all digital standards. The compact but flexible all-in-one-box concept allows various options to be integrated, which simplifies logistics and handling when sites are difficult to access.

The transposers cover analog TV standards as well as digital TV standards (DVB-T, DVB-T2, DVB-H, ISDB?T, ISDB-TB, DTMB, CMMB, ATSC and ATSC Mobile DTV). For digital sound broadcasting, the transposers support broadcasts in line with the DAB, DAB+ and T-DMB specifications. If necessary, a transposer can be easily converted from analog to digital TV without modifying the hardware. The output powers range up to 100 W for COFDM based standards, up to 150 W for ATSC/ATSC Mobile DTV, up to 250 W for analog TV and up to 250 W for DAB(+)/T-DMB. The broadband output stages are based on powerful LDMOS and VMOS transistors and feature high efficiency. Since the components used have a high level of integration, the transposers are favorably priced and can be delivered quickly, even if they are ordered in large quantities..
