This type of modulator supports the DVB-С standard.  DVB-С Modulator is controlled by our own developed VCC software by Ethernet. DVB-C Modulator has input BNC connector and can be produced with N-, F- or SMA-type of output connectors by order. The DVB-С Modulator is professional device and it is usually used by TV operators for modulation up to QAM256.


  • supports symbol-rate up to 45 Msymb/s
  • output frequency range of 70 – 865 MHz
  • supports constellations up to QAM256
  • has high modulation error rate (MER)
  • has output level of 80-107 dBµV
  • can be produced from 1 to 32 independent modulation channels
  • optionally has 10 MHz reference and DC injection


  • remote control by Ethernet
  • if power is lost all saved settings are recovered in the device after restoration of supply
  • integrated over‐voltage protection (by power supplying)
  • integrated over‐load protection (by power supplying)
  • integrated short‐circuit protection (by power supplying)
