Universal SDR receiver for VHF/UHF band
Advanced demodulator API available
Optimized for Software Defined Radio
Description
DTA-2131 Features
- Tuner, I/Q demodulator and sample-rate converter, optimized for use with SDR technology (Software Defined Radio = demodulation in software)
- SDR enables advanced features such as full demodulation of DVB-T2 to T2-MI, or forwarding all IP packets from ATSC 3.0, or MER per OFDM carrier, transfer functions, etc.
- Hardware sample rate converter for obtaining I/Q samples at a convenient sample rate
- MER measurements in OFDM up to an accuracy of 42dB
- Programming interface (DTAPI) is fully compatible with other DekTec adapters
DTA-2131 Applications
- Network monitoring of ATSC, ATSC-3, DVB-T, DVB-T2, DAB+, DVB-C2 or ISDB-T with advanced measurements
- Universal receiver
- Receiving DVB-T2 as full T2MI stream
- Recording of I/Q samples
- Front end for SDR experiments
