The ATSC-5000-DTT translator features a powerful 1RU receiver/ exciter that demodulates the off-air signal for clean signal retransmission.
The translator features 0PPM for carrier frequency and symbol clock frequency. The translator also retains the original legacy and MH symbol order and supports both MFN and SFN operations.
The receiver features a wide dynamic RF channel input range and high sensitivity all while providing strong adjacent channel rejection. The front panel includes a receive signal level indicator and demodulator SNR allowing easy installation and setup in the field with minimal equipment.
The ATSC-5000-DTT translator integrates Digital Adaptive Precorrection ( DAP) technology, which provides superior performance that is unattainable using any other correction technique. This technology allows for simple and easy setup and maintenance of a high performance transmitter system.
DAP technology provides unsurpassed digital correction of all distortions created by a DTV transmitter system. These distortions include nonlinear distortions created by active amplifier devices, such as amplitude and phase distortions along with correction for memory effect.
Additionally DAP corrects linear distortions created by the transmitter’s high-power passive RF system, such as group delay and frequency response distortions maximizing the SNR performance.
The ATSC-5000-DTT translator incorporates local control and monitoring using a newly enhanced user interface front panel with backlit LCD display, LED’s, and menu driven push buttons. Local access includes menus for initial setup, configuration status, and control functions.
The front panel also displays the real time output RF shoulder levels as well as the SNR performance The ATSC-5000-DTT translator can also be remotely controlled using the Web GUI interface with nothing more than a PC running a standard web browser. The Web GUI allows users to retrieve information such as SNR, lower and upper RF shoulder measurements, user configuration, and alarms.
The ATSC-5000-DTT is fully compliant with the ATSC A/53 DTV standard. It features a frequency tolerance specification to within 1 Hz and true frequency agility across the entire UHF Bands 4 and 5. It is also available in VHF Band 1 or VHF Band 3 (users need to specify UHF vs. VHF 1 / 3 at time of order). The ATSC-5000-DTT translator is also compatible with the ATSC A/153 Mobile DTV standard.
The translator performs the post processing and modulation functions for Mobile DTV broadcasting.
Upgrades are possible either locally or remotely via a WAN connection to the translator(s).
