The PCI-8 is an 8-channel, PCI-based AE system on a board. Its 8 high-speed AE channels offer simultaneous AE data acquisition, waveform processing and data transfer. The board’s standard PCI form factor enables installation in standard PCs, as well as in any of Physical Acoustics’ specialized AE system chassis, while the PCI bus enables AE data transfer at speeds of up to 132 Mb/s, at a frequency range of 1 kHz to 400 kHz.

The board’s built-in feature extraction capability provides high-speed transient data analysis at high hit rates. Extracted features include time of 1st threshold crossing, time to peak, peak amplitude, and more. Additionally, each PCI-8 board is capable of supporting up to 2 analog parametric inputs at a 10 kHz sample rate. The board’s power-efficient design makes the board well suited for portable applications.

When configured as part of a SAMOS AE system, the PCI-8 offers a comprehensive solution for AE data acquisition and analysis. Multiple PCI-8 boards can be used side-by-side in a single chassis for additional AE channels.

Physical Acoustics’ Windows-based AEwin™ data acquisition and analysis software enables features such as advanced 2-D and 3-D graphing of collected data, location determination, as well as software selection of filtering for each AE channel, from a choice of 4 high pass and 4 low pass filters.


  • Low power consumption.
  • 8 digital (16-bit A/D) complete AE channels on one full-size PCI card.
  • PCI-bus provides AE data transfer rates of up to 132 Mb/sec to a PC computer.
  • 4 High Pass, 4 Low Pass filter selections for each channel, totally under software control.
  • Up to 2 parametrics on each PCI-8 board with update rates up to 10,000 readings/second (when attached to hit data).
  • Designed with multiple FPGA’s and ASIC IC’s, to provide extreme high performance and minimize components and cost.
  • Hit LED drivers are built within the PCI-8 board so that AE activity LED’s can be attached directly.
  • Built-in AE feature extraction provides high speed transient data analysis at high hit rates.
  • Built in waveform processing with DMA & Bus Mastering transfer for high speed transfer of waveforms on all 8 AE channels.
  • Digital signal processing circuitry virtually eliminates drift, thereby achieving high accuracy and reliability.
