ATSC-T Modulator

Product Description

Function: ATSC-T 8VSB Modulator Full Comply with ATSC A/*3 with ASI and SMPTE**0M Input Interface TLS***3 ATSC-T Modulator is *-VSB ATSC-T modulator. It s video data stream, through DVB-ASI and SMPTE***0M interfaces, and outputs *0~*5MHz IF and **0~**0MHz RF signals after ATSC*-VSB modulation. ATSC-T modulator supports 8VSB encoding and modulation of ATSC-T A/*3 standard. The system can be controlled and upgraded online. It is widely used in ATSC-T digital broadcast network establishing and ATSC-T STB design testing. Features: - Completely comply with ATSC A/*3 standard - RS encoding, data interlacing, Trellis encoding - Constellation mapping: *-VSB - Channel bandwidth: 6MHz - Comply with EN****3 ASI and SMPTE **0M interface standards - IF: *0MHz ~*5MHz, 1Hz Stepping - RF: **0MHz~**0MHz, 1Hz Stepping - Excellent modulation performance: EVM, MER, SNR, Bandwidth Shoulder Ratio, etc. - Front panel and IP remote control - Support remote maintaining, monitoring and software upgrading - DVB-ASI and SMPTE***0M s; support auto-switching and hot standby - Support external *0MHz clock ; adopt internal homoeothermic crystal; frequency stability:1ppm Technical Specification - RF Output MER ≥*8dB Bandwidth 6MHz Bandwidth Shoulder Radio ≥*0dB In-band Flatness ≤±0.5dB Carrier Phase Noise *-*/*@********************�*2dB - Channel Coding and Modulation Bandwidth 6MHz - Internal Clock Output Level 0dBm±3dB (*0MHz) Frequency Stability 1PPm - External Clock Input Level *5dBm~*0dBm (*0MHz) Input Impedance *0Ω *****
