DVB-S2 / DVB-S Modulator unit is professional equipment for using by operators of television networks and performs modulation from QPSK up to 32APSK. Modulator has from 1 to 6 independent channels formed in a single housing 19” height 1U or 2U. This device performs modulation digital stream RF carrier frequency in a full L-band range (950 MHz-2150 MHz) according to the standards DVB-S, DVB-S2

KEY FEATURES:

  • Frequency range: full L-band 950 - 2150 MHz
  • Support DVB-S and DVB-S2 standards
  • Constelation QPSK, 8PSK, 16APSK and 32 APSK
  • Hight modulation error rate (MER) >27 dB
  • Input bitrate 1–32 MSymbol/s in 1 kSymbol-steps
  • Output level 80-107 dBµV
  • Optionally 10 MHz reference and DC injection
