The U5303A is a two channel PCIe 12-bit digitizer with programmable on-board processing. This ADC card occupies a single full-length PCIe slot of the host PC and captures signals on 2 channels, from DC to 2 GHz at 1 GS/s, 1.6 GS/s or 2 GS/s. Featuring DDR3 acquisition memory up to 4 GB, this digitizer includes a Xilinx FPGA allowing the implementation of custom real-time processing algorithms.

The U5303A digitizer provides several firmware options:

  • The digitizer firmware option (-DGT) with up to 2 GS/s, 1.6 GS/s, 1 GS/s or 500 MS/s per channel, included in most configurations
  • The interleaved option (-INT) that allows two channels to be combined to reach 4 GS/s, 3.2 GS/s or 2 GS/s in one channel acquisition mode
  • The real-time sampling and averaging option (-AVG) that performs waveform accumulations at up to 4 GS/s on single-channel and 2 GS/s on dual-channel
  • The real-time signal peak detection option (-PKD) that performs peak detection and enables generation of a histogram of peak versus time for successive acquisitions
  • The simultaneous acquisition and readout option that enables longer acquisition time, allowing to acquire signals while reading the previously acquired data, either continuously (-CSR) or using triggered multi-records (-TSR)

Besides, this digitizer offers the following application options:

  • The streaming and recording applications that provide a real-time digitizer data recorder (-CB0) with digital down-conversion capability at 1 GS/s (-CB1), 1.6 GS/s (-CB2) or 2 GS/s (-CB3)
  • The swept source OCT options that enables real-time OCT signal processing and supports A-scan rate from 50 kHz to 100 kHz (-SS1) or A-scan rate of 200 kHz (-SS2)
