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
