ATSC TRANSMITTER
1.1 DESCRIPTION
The ATSC TRANSMITTER is an 8-VSB ATSC professional exciter, designed for the most demanding
digital TV broadcasting applications. It integrates a modulator module with up-to-date FPGA technology and
advanced digital signal processing algorithms in order to generate an absolutely accurate output 8-VSB signal,
with exceptionally optimized modulation and the output filtering techniques.
Very high linearity performances are possible thanks to very careful RF design over the entire VHF and UHF
bands and with an optimal digital precorrection engine working simultaneously in the time and frequency
domains. A high degree of reliability is guaranteed, moreover, by the use of oversized cooling devices and by
control circuits operated by modern microprocessor technologies.
The ATSC TRANSMITTER can be used as a stand-alone 5W RMS transmitter or as a driver stage for
amplifiers of greater power. The excellent spectral purity of the conversion oscillator lets the ATSC
TRANSMITTER radiate an 8-VSB signal with an excellent MER value.
The ATSC TRANSMITTER is equipped with a powerful ASI/SMPTE inputs management block which
allows to manage the Transport Stream (TS) inputs in a fully redundant configuration, thus significantly improving
the reliability of the whole broadcasting system in every operating condition.
The ATSC TRANSMITTER is totally compliant to the A/53, A/54 and A/64 ATSC recommendations with
6MHz output channel bandwidth, in VHF and UHF bands.
