TRANSCAST Pemancar TV Digital DVB-T2
TRANSCAST High Pemancar TV Digital DVB-T2
• Built-In AGC
Dualcast Transmitter is a very innovative and unique solution especially designed to meet transmitter manufacturers’ demand for integrating a high-end and cost-effective modulator/exciter within their own transmitter design.
Dualcast Transmitter comes as the ideal choice for any Transmitter manufacturers’ who are willing to hit new market opportunities with limited investment and in a very short-time period. It features several key functionalities such as built-in Automatic Gain Control (AGC), embedded monitoring (SNR, Shoulder levels, forwarded & reflected power levels) as well as comprehensive to integration process and to drive the Power Amplifier stage in the most efficient way.
Transmitter Digital Adaptive Precorrection circuits, permits to run transmitters very closed to their saturation limit, with unequalled RF signal performances and allowing significant gain in transmitter Power Efficiency.
World-wide leading and proven DVB-T2 technology
Dualcast Transmitter inherits from the world-wide leading DVB-T2 technology in use in most of the DVB-T2 commercial networks today in operation. DVB-T2 modulation core brings unmatched standard usage flexibility supporting MFN System A, SFN System B, SISO/MISO, Multi-PLP layered modulation and hybrid T2-Base & T2-Lite simultaneous transmission.
