The new HPA 300-3500 DTV AC transmitter of the Ecostone family is a technological platform capable of providing a DTV output signal up to 3500W. The Digital Exciter modulator board is 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 a standard 19 ″ rack, with optimized energy consumption.
The DTV AC HPA 300-3500 uses the latest LDMOS technology and provides the necessary modulation in accordance with the required 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 DTV AC HPA 300-3500 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. Remote control and monitoring options available.
