1x RF out 75-Ω F-type (monitor)

PC requirements

OS Windows XP, 2k3/2k8, Vista, 7, 8/8.1, 10 Linux  ≥2.6.18, 3.x, 4.x

Powering options

  • Through the Ethernet cable using:
    - IEEE 802.3af compatible PoE switch
    - PoE midspan power inserter
  • With DTE-PWR2 power adapter

Hardware limitations

  • Channels must be grouped: overall spectrum of the DTE-3114 cannot be wider than 32MHz
  • All channels must operate in the same mode and with the same symbol rate
  • Not supported:
    - Scrambling of incoming Transport Streams
    - VBR input streams
    - SPTS-to-MPTS multiplexing
     (possible in software with MuxXpert)

Firmware 

  • DTE-3114 firmware    

Dektec models are most often differentiated by the sufix e.g. SD, SXP etc., where suffix specifies the SW licence
  • SP = Stream Player (allows you to play/modulate transport stream files, so this makes sence for devices with Output interface)
  • SXP = Stream Xpert (this is MPEG TS ANALYZER, what makes sence for Input devices)
  • SLP = Stream Xper Lite (very limited alternative of SXP, de facto allowing mainly capturing MPEG TS, again makes sence for Input devices)
  • RX = RFXpert RF signal analysys
  • SY = SD Eye (video analyzer)
  • J = Jitter
  • DGL = Dongle license for non Dektec devices
Meaning of abreviations used in beginning of Dektec model names
  • DTA = Dektec adapter (typically PCI, PCI-e)
  • DTU = Dektec USB device both USB-2 and USB-3
  • DTE = Dektec Ethernet standalone networked device
  • DTC = Dektec software license
