      產品詳細介紹Product Introduction

      High-end satellite receiver for PCIe

      Professional-grade satellite receiver card with high-quality RF measurements.
      Ideal for satellite monitoring, modulator testing and high-speed data distribution.

       

      Features

      • FPGA-based DVB-S2/S2X demodulator (no CPU cycles consumed) with calibrated channel-power and MER measurement.
      • Supports VCM, ACM, MIS (multiple input streams), GS (generic stream) with access to baseband frames (BBFRAMEs) in L.3 format.
      • Hardware demodulator can be bypassed to obtain I/Q samples for recording or SDR.


      Applications

      • Creating comprehensive satellite-network monitoring solutions for DVB-S2 and DVB-S2X.
      • Validation of DVB-S2/S2X modulators.
      • High-speed satellite data distribution.


      Block Diagram

      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 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.
