Description
TWISTER 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. TWISTER 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 WEB GUI control, to ease integration process and to drive the Power Amplifier stage in the most efficient way. TWISTER Digital Adaptive Precorrection circuits, powered by TeamCast GAP® - Green Adaptive Processing - algorithm, 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
TWISTER inherits from the world-wide leading DVB-T2 technology designed by TeamCastalready in use in most of the DVB-T2 commercial networks today in operation. TeamCast 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. |
