Upstream decryption: Compact headend with DVB-S output

POLYTRON PCU 4141

The new triple tuner headend PCU 4141 with SAT IF output converts DVB-S/S2, DVB-T/T2 or DVB-C signals into DVB-S.
The output signals can be fed directly or via multiswitches into the SAT IF distribution system.
The compact headend features 4 built-in CI slots which enable central decryption of TV and radio programmes.

  • Triple-Tuners: input signals DVB-S/S2, DVB-T/T2, DVB-C freely selectable
  • mixed reception possible
  • output signal DVB-S / QPSK
  • output level 90 dBµV / attenuation 0-12 dB
  • MPEG 2 and MPEG 4 capable
  • 4 CI slots
  • dynamic PAT and PMT with encrypted programmes
  • transponder content can be erased
  • NIT / PAT / SDT adjusting
  • built-in LNB power supply
  • temperature dependent fans
  • programming and updates via USB and LAN
  • filter PCU-F001 and inline amplifier SV 100 included in delivery
  • made in Germanyy

PCU 4141 Anlagenbeispiel


The external bandpass filter PCU-F001 allows feeding the headend‘s output signals into every SAT polarisation. The filter rejects the frequency range 950–1110 MHz which gives place for the PCU 4141‘s four output transponders. By using the filter, the available bandwidth is used effectively.
