Introduction

It is professional equipment for re-modulating.

It is designed to convert terrestrial digital 8-VSB RF broadcasting signal into standard IF band and then demodulate it into transport stream signal.

After demodulating, TS signal is modulated into the

8-VSB(ATSC) and re-transmit RF signal in UHF/VHF band. It has suitable feature to prevent from digital signal transformation and distortion on transmission process.

Feature

• RF input 8-VSB(ATSC) terrestrial digital broadcasting

signal input

• Enables 8-VSB modulator to allow 1xASI input (option)

• Support 8-VSB(ATSC) decoding and modulation

• 8-VSB (ATSC) RF signal output

• Simultaneous outputting 8-VSB(ATSC) and Analog

• User adjustable input and output

• PCR Jitter: = ± 200 ns

• MER After Equalizer: 42dB

• Group Delay as ± 20 ns

• Phase Noise VHF -105 dB@20KHz, UHF -103 dB@20KHz

• Frequency: 54 ~ 870MHz

• Controlling & Monitoring via Front Panel

Competitiveness

• Optimized Re-modulator with Digital output

• Save your installing cost with simple set-up and operation

• Useful solution for DTV transition

• Easy set-up via front panel and SNMP

Options

• 8-VSB RF signal output with controlling and monitoring via SNMP

• 8-VSB RF signal output + analog signal output
