Multi-standard TV Exciters

Description

Multi-standard TV Exciters

ETVDSL10 is a new generation of UHF/VHF multimode Exciters, Dual Cast Digital Exciter of the Broadcast Eletec family is a High-End equipment for modulation and digital signal processing, based on the most advanced technologies – a FPGA (Fiel Programmable Gate Array) and Direct Digital Up-Conversion RF. Extremely compact and efficient equipment enclosed in 1 standard 19 ″ rack unit, with optimized energy consumption.

The integrated software, accessible both locally and remotely, allows you to switch between analog and digital TV broadcasting. The digital modulator provides the necessary modulation according to the chosen transmission standard.

The modulation process is completely digital for both Audio and Video to provide high performance and stability, and includes Linear and Non-Linear precorrection.

The exciter is equipped with a complete set of audio inputs and an internal GPS receiver (1pps and 10Mhz) for the necessary synchronization. An intuitive local interface displayed on the LCD display allows real-time monitoring and configuration of equipment parameters.
