Terra TTQ420C Twin DVB-T/T2/C - DVB-C transzmodulátor CA interfésszel

Moduláris rendszerekhez

Converting of 2  DVB-T/T2/C modulated 
input signals into 2 QAM modulated DVB-C channels.

  • common interface
  • TS processing:

              service multiplexing - any input to any output
              PCR restamping
              PSI/SI regeneration
              NIT generation
              PMT version monitoring

  • Web control and SNMP monitoring
  • loop through RF distributing at input and output
  • DIN rail or wall mounting
  • robust die-cast housing
  • connectors:

          RF input/output - type F
          Ethernet control interface - RJ-45
          2xCI ports - PCMCIA (tdq420C, ttq420C)
          screw terminal block for DC entry
          power distribution bus
