The new DTV AC HPA 300-3500 Transmitter of the Ecostone family is an advanced technological platform able to deliver up to 3500W RF DTV output signal. The Digital Exciter modulator board is based on the latest technologies - an FPGA ( Field Programmable Gate Array ) and Direct Digital RF Up-Conversion. An extremely compact and efficient equipment with reduced consumption and dimensions of 19" Rack Standard.
The DTV AC HPA 300-3500 takes advantage of the most advanced LDMOS technology and provides the necessary modulation according to the chosen trasmission standard.
The modulation process is fully digital for both Video and Audio to grant high performances and stability, and includes Linear and Non Linear pre-correction.
The DTV AC HPA 300-3500 is equipped with Audio, Video and ASI Inputs with seamless switch and with an internal GPS receiver ( 1pps and 10Mhz ) for the necessary synchronization. An intuitive Local Interface displayed on the LCD and controlled through a rotative KNOB allows real-time monitoring and configuration of the equipment parameters.
Remote operation and monitoring option available.
