R&S®SLx8000 UHF/VHF Transmitter Family

Low-power transmitters for digital TV

General Information

The new SLx8000 family of products

To meet modern TV transmission requirements, existing infrastructure needs to be renewed or further expanded. This affects stationary TV based on the new DVB-T and ATSC standards as well as mobile TV based on the DVB-H standard.

Thus, an enormous number of new transmitters or retransmitters will be required in the very near future, especially for low-power applications. Despite the high quantities that will be needed, budgets should not be overstrained. Yet high transmitter quality is crucial when it comes to preventing nationwide transmitter replacements or reworking, which would entail enormous follow-up costs.

Space in low-power transmitter sites is often very tight, and the voltage supply is often not ideal. Moreover, the transmitters are sometimes difficult to access. Thus, high requirements are placed on transmitter ruggedness, flexibility, compactness, and easy transport.

To meet these demands, Rohde & Schwarz has developed the SLx8000 family of transmitters. The new transmitters, which are rugged, compact, and flexible, complement the company's low-powerrange portfolio. Due to the components' extremely large scale of integration, the instruments are favorably priced and can be delivered within a short time. And these advantages come with the high quality Rohde & Schwarz stands for – also when it comes to high quantities.

Analog and digital networks

In addition to the new digital networks, the R&S®SLx8000 UHF/VHF Transmitter Family can be used in existing analog networks to modernize low-power transmitters. The R&S®SLx8000 UHF/VHF Transmitter Family supports the DVB-T/-H and ATSC standards as well as the analog B/G, D/K, M/N, and I TV standards. The highly compact 19" instruments for the UHF and VHF frequency ranges cover the power range up to 100 W DVB-T/DVB‑H, 160 W ATSC. Up to 10 W, the transmitters require only two height units; for the range from 25 W to 100 W, three height units are sufficient (power values referenced to DVB-T/-H).

An SNMP agent, NICAM sound and a parallel interface for remote control are optionally available. Local operation can be conveniently performed either via display and keyboard, or via web browser and laptop. The transmitters support the (n+1) including (1+1) standby configuration.
