  • Universal parallel port for receiving or transmitting 8-bit data with valid and sync at clock rates up to 108MHz
  • Software-selectable M-LVDS or LVTTL
  • The parallel port supports several modes, including DVB-SPI with boosted clock range, a fixed-clock transport-stream mode, serial with explicit clock and BT-656 for uncompressed SD video
  • Serial port is software-selectable input or output, DVB-ASI or SDI
  • External clock input that can be used as master clock for serial and/or parallel port
  • BNC connector on PCI bracket can be used as serial port (default) or as external clock input by reconnecting coax cable to the ex-ternal clock input MCX connector
  • Short-circuit detection on parallel port
  • Each port has on-board 32-Mbytes buffer


  • General purpose lab card for generating and capturing of (un)compressed digital video and other 8-bit or 10-bit signals
  • Universal stream station

  • DTa-2142 Leaflet    

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
