Digital TV Exciter
The DAR-1000A re-transmitter (Digital TV Exciter) features forward error correction (FEC) during demodulation of air broadcasting input signals. The VSE receiver of DAR-1000A directly convert air signal into standard TS signal. These signals are then remodulated onto a different frequency, Making a MFN (Multi-frequency network) possible.
The DSP (Adaptive Corrector) automatically generates correction factors of non-linearity / linear distortion and updates the correction table without interrupting program service.
Optimum signal quality and service coverage are maintained, protected from the effects of ambient temperature, aging and other factors, Furthermore, the Adaptive Corrector is capable of analyzing feedback signals from the TX output, including inter-modulation level, Group delay, Frequency response and SNR value.
Consequently, automatic adjustment of the inter-modulation and frequency response values greatly reduces the time required for maintenance.
