Block diagram

Real-time processing in the FPGA

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 ADC card provides several firmware options:

The digitizer firmware option (-DGT) allows to easily acquire a single waveform or multiple trigger signals, at high trigger rate.
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. It includes features like baseline stabilization, noise suppress accumulation or a self-trigger mode for noise reduction.
The simultaneous acquisition and readout option that enables longer acquisition time, allowing to acquire signals while reading out the previously acquired data, either continuously (-CSR) or using triggered multi-records (-TSR)
