UT-100 - Features


USB based modulator/demodulator with support for EN 300-744 DVB-T transmission and reception.


Powered from the USB bus, so no external power adapter is required


Full hardware modulation/demodulation, no host CPU computation required.


 


Modulator (Transmitter):


Direct digital conversion to 50~950MHz and 1200~1350 MHz for excellent signal quality


UT-100A/UT-100B/UT-100C support configurable bandwidth from 2MHz to 8 MHz.


(Note: UT-100D supports only receiving and does not support transmitting.)


Support only non-hierarchy mode


Programmable digital attenuator


Free Windows Stream Player


Free Windows and Linux SDK


 


Demodulator (Receiver):


UT-100A supports Worldwide Free to Air Digital Terrestrial (DVB-T) Receptions (5/ 6 / 7 / 8 MHz bandwidth)


UT-100B/UT-100D is a special custom version (supporting 2/3/4 MHz bandwidth) for amateur HAM TV reception.


(Note:UT-100C supports only transmitting and does not support receiving.)


Standard Windows DVB-T BDA driver provided


Windows Media Center compatible DVB-T TV tuner


Note: the receiver frequency range supported is 50~950MHz.


 


UART Data Demux


While working with BDAViewer+, UT-100 receiver supports UART data demux.


A typical application is to mux NMEA GPS info in the transmitted stream in the Tx end of a UAV, UT-100 decodes the stream, and feed the demux’ed NMEA GPS to Google earth to track the UAV.
