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)
Documents
- DTE-3114 Leaflet
- DTE-3114 Manual
- DTE-MIB (General MIB for DTEs)
- DTE-QAMMOD-MIB (QAM Modulation MIB)
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
