DTA-110T Features
· OFDM modulator with support for DVB-T and DVB-H (EN 300 744)
· Low cost, low power and flexibility achieved by performing part of the modulation process in software
· Integrated UHF Upconverter with on-board 400…862-MHz synthesiser
· RF output can be connected directly to a digital terrestrial receiver
· Programming interface (DTAPI) compatible with other DekTec digital-video output adapters
· With DtLoop: modulator replacement
· PCI rev 2.2, 32 bit, 33 or 66 MHz bus
DTA-110T Applications
· Driving digital terrestrial receivers for demos, at shows, in electronics stores
· Set-top-box development, repair, production testing, performance testing
· Signal validation: check out whether receivers can handle a new transport stream
· Output adapter for generating an OFDM modulated RF signal directly from your custom application
PC Requirements
· PC selection is critical because of software processing. The DTA-110T will not operate well in PCs that lack sufficient CPU power, memory- or PCI bandwidth
· P4@2GHz minimum, or equivalent AMD
· 512 MB RAM minimum
· Windows-2000/XP/2003, no Linux support
· Motherboard chipset should not use integrated graphics, e.g. Intel 82865G does NOT work
