Professional-grade satellite receiver card with high-quality RF measurements. Ideal for satellite monitoring, modulator testing and high-speed data distribution. The card comes with full decoding and analysis of DVB Carrier ID (DVB-CID).

The main path of the DTA-2132 consists of a wide-band L-band tuner, 12-bit I/Q analog-to-digital converter, DVB-S2/S2X demodulator and decoder, L.3 packetizer, FIFO, DMA controller and PCIe interface. Constellation points are sampled after the demodulator, while LDPC error-rate and other statistics are gathered after the decoder. A secondary I/Q path is used for multiple purposes: estimating the spectral characteristics of the input signal, DVB-CID demodulation, and sending I/Q samples to a user-space application for SDR, recording or other purposes. A third path low-pass filters the I- and Q samples and estimates the signal power, corrected by calibration tables. The DTA-2132 also contains an 18V/600mA LNB power inserter with over-current protection, as well as a DiSEqC-2.0 22-kHz LNB-control signal inserter. Finally, a temperature monitoring unit controls fan speed to keep the board cool.
