SA1 8-bit DAQ card

from 500 MS/s to 2 GS/s, FPGA signal processing

Compact, stable and cost effective


SA1 DAQ Card, 8-bit, from 500 MS/s to 2 GS/s, FPGA signal processing

The SA1 provides signal acquisition solutions from 500 MS/s to 2 GS/s, based on 8-bit high-speed DAQ cards / digitizers, with FPGA processing. The SA1 DAQ card/module (also named ADC card or digitizer) is particularly suited for OEM’s applications requiring a reliable, stable and cost effective waveform acquisition solutions with on-board real-time processing capability.

Acqiris SA1 8-bit ADC cards implement a proprietary low noise and low distortion front-end, enabling excellent signal fidelity. The SA1 brings high signal performance and lower consumption in a reduced footprint.

It offers an ideal data acquisition platform for many commercial, industrial and measurement embedded systems.

The SA1 ADC cards are more compact than the previous generation of 8-bit digitizers and occupy a single full-length PCIe slot of the host computer. The consumption has also been reduced by half.

In addition, there is no need for any additional power supplying cabling than the PCIe connector power supplies.

Real-time processing in the FPGA

Featuring a large DDR memory for long acquisition time, the hardware also includes a Xilinx FPGA allowing implementation of real-time processing algorithms. This powerful feature allows data reduction to be carried out on-board, minimizing transfer volumes and speeding-up analysis. It also reduce the resources and cost required for the host computer.

Depending on your application, the SA1 DAQ Solution includes a digitizer or an applicative firmware.

The standard digitizer mode includes:

  • Digitizer initialization and calibration
  • Single record or multi-record acquisition
  • Management of channel triggering for best synchronization
  • Distortion reduction
  • Lower sampling rate (Decimation) down to 15.625 MS/s

The real-time sampling and averaging option enables synchronous real-time sampling and accumulation up to 2 GS/s on a single-channel and 1 GS/s on dual-channel.

The streaming capability, with simultaneous acquisition and readout for successive triggered acquisition (CST) is dedicated to applications requiring no trigger loss, achieving longer recording time when compared with standard digitizer mode. Thanks to the PCIe Gen 3 interface, the card offers maximum data transfer rate to the host computer.


More than a digitizer, the SA1 solution allows the synchronization of the system thanks to:

  • 3 programmable IOs
  • 3 synchronized output (pulse generation)

These signals are managed by the FPGA. The generated pulses are configured by user and synchronized with the trigger, for a tight instrument control.
