Rohde & Schwarz has added to its portfolio of low-power VHF transmitters with the introduction of the R&S TLV9. The new model is designed to operate in VHF band III with an output power of 50, 150 or 300 Watts from a single 2U box.

Rohde & Schwarz: The new TLV9 low-power VHF transmitter for DAB+ and DTV

The TLV9 targets a number of markets including DAB and DAB+ networks, mainly in Europe, as well as DTV network operators using VHF band III for DVB-T/T2 or ATSC in Italy, Finland, the US and Australia.

The TLV9 VHF transmitter is claimed to set the benchmark for the low-power transmitter class with up to 30% efficiency, offering power savings over other low-power transmitters that are only 18% efficient.

It has been designed for simple operation, providing a clear picture of the current operational status through an intuitive operator interface. Engineers can easily define boundaries for operational parameters, such as target shoulder distance or the warning level for a minimal Modulation Error Ratio. Based on this input, the transmitter works according to these parameters and provides constant feedback via Simple Network Management Protocol without the need for external monitoring equipment.

This level of automation and improved operation is claimed to reduce infrastructure complexity and decrease stress on the system engineer, since virtually all system analytics are performed automatically by the transmitter system. The TLV9 is designed to permanently operate at high temperatures – up to 45°C at full power.

Designed to be future-proofed, the TLV9 offers cost savings over the transmitters’ entire life thanks to energy efficiency optimisation, premium RF components and advanced thermal design.

The TLV9 comes includes efficiency measurement and signal quality analysis, along with a self-monitoring function that provides instant feedback on operational parameters and clear diagnostic information in the event of a fault.

“Thousands of R&S TLx9 transmitters are in operation around the world. They prove their exceptional reliability every day, demonstrating that Rohde & Schwarz low-power transmitters perfectly satisfy network operators’ needs for minimal operating costs and maximum availability,” claimed Manfred Reitmeier, VP transmitters and amplifier systems at Rohde & Schwarz. “This new transmitter clearly differentiates Rohde & Schwarz in a competitive market. Already we have received significant interest from customers.”
