2 ch DVB-S-S2 Modulator v.2.0

  • Description
  • Downloads

It supports modulations from QPSK to 16APSK and sybol-rate up to 44Msymb/s.

Using our 2 ch DVB-S-S2 Modulator v.2.0 you're able to obtain both user-friendly management interface (connection by Ethernet) and stable 24/7 equipment including up-to-date parameters which are listed in parameters tab.

KEY FEATURES:

  • has 2 independent modulation channels
  • output frequency range of 950-2150 MHz
  • supports symbol-rate up to 44 Msymb/s
  • supports constellations up to 16APSK
  • has high modulation error rate (MER), more than 30 dB
  • has output RF-level of 80-100 dBµV
  • integrated output RF power attenuation

 MAIN FUNCTIONS:

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