UT-100C - Features
USB based modulator with support for EN 300-744 DVB-T transmission.
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
Support only non-hierarchy mode
Programmable digital attenuator
Free Windows Stream Player
Free Windows and Linux SDK
UT-100C Host Requirements
· CPU: Intel, AMD, ARM, MIPS
- 128MB RAM of system memory or above
- Higher CPU and memory required if DVB-T audio/video decoding is needed
· One available USB2.0 or 1.1 port
Note: USB 1.1 can only support 3~5 Mbps stream data rate.
