TXrenix, ATSC-M/H Re-Transmitter & Gap-Filler, features FEC (Forward Error Correction) during demodulation of ATSC-M/H input signals. The ATSC-M/H reference receiver of TXrenix directly converts air signal into standard TS signal. These signals remodulated onto a different frequency, making a MFN(Multi-Frequency Network) possible. Besides, TXrenix automatically generates error correction factors of linear/non-linear distortion and updates the correction table without interruption of current program service. Especially, TXrenix can analyze feedback signals from the TX output, including inter-modulation level, RF waveform, Group delay, Frequency response and SNR value and so on.
