- Datasheet
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

- Versatile product Review by Dab
- Despite the fact this product is physically bigger as you would expect from the image, it is extremely versatile signal generator I use to take with myself for field testing. (Posted on 1/2/2018)
