The Physical Acoustics, PCI-8 "The 8-Channel AE System on a Board" with "simultaneous" Digital Signal Processing (DSP) of acoustic emission (AE) of waveforms and features is the "central" component of a series of bold AE Multi-Channel systems.�The "Sensor based Acoustic Multi-channel Operation Systems" (SAMOS) represent the latest introduction of advanced AE systems by PAC. Such systems are tailored for low power and extreme compactness.
PCI-8 Subsystems occupy one full-size PCI slot in or computer chassis and can be implemented inside most standard PC's or inside one of PAC's four (4) rugged, multi-channel SAMOS system chassis, which include SAMOS 80/48/32 and µSAMOS.�Such systems are based on PAC's known parallel processing architecture, process simultaneously waveform and AE features and are extremely cost competitive for today's advanced digital AE market.�As with all other PAC systems, SAMOS multi-channel systems are powered by the AE experienced based Windows PACwin Software Suite operating at outstanding waveform/features AE hit data rates.
The SAMOS 32 AE system is geared for laboratory or field use, holding up to 4 PCI-8 cards for up to 32 AE channels of operation.�Based on a heavy-duty desktop PC computer chassis, the SAMOS 32 has added features for reliable day-to-day operation, including extra cooling, ventilation and the latest powerful PC computer motherboard.�This PC computer and motherboard form factor provides the most economical, high performance AE system for users with tight system budgets.�The SAMOS 32 retains all the features of a full AE system, including activity Hit LED's on the front panel and digitally controlled, full featured, high fidelity audio monitor. The system is 17"W (43cm), 17"D (43cm) and 6"H (15.2cm), and weighs 26 lbs.

- Software available for the SAMOS includes the state-of-the-art PACwin Software Suite. With 25 years of acoustic emission application experience behind it, this Suite is comprised of three individual software packages (purchased separately); these are: AEwin real-time Windows acquisition, replay and analysis software, AEwinPost post analysis software and NOESIS, the most complete Pattern Recognition (supervised or unsupervised) and Neural Networks software in the AE and NDT market today. (Ask about our free software drivers for reading competitive system data files... so that their AE data makes sense.)

Standard 16-bit PCI hardware and 32-bit Windows software allows for maximum flexibility by customer of using a PC or a notebook. No need to change "home made" PC's, but ability to take advantage of today's PC speeds readily available with high performance PCI busses. Multiple AE channels are easily synchronized for multiple location algorithms.
- SAMOS Multi-channel AE Systems are supported by PACs Windows Platform of PACwin Suite.
- All software runs in Windows 98, Millennium, 2000 and XP, thus taking advantage of standard features as multi-tasking, graphic user interfaces, etc. and giving the ability to change AE parameters during test operation.
- Multiple location algorithms are available including linear, Tank bottom planar, cylindrical, spherical (with ASME weld zones), 3-D, advanced Non-Linear Regression (NLR) location, and over-determined planar location for exceptional accuracy. All location algorithms include amplitude correction tables/curves for auto-sensors placement and more accurate location and AE intensity calculation.

- Acquisition or Replay. Can run multiple sessions (Acquisition and Replay at the same time)
- Uses full Windows resources including printing, network, multitasking, etc.
- Play your existing DTA files
- Multiple Graph types including 2D, 3D (fully rotateable), line, point plots, histograms, multiple plots within a graph, waveforms, FFT�s, and more

AEwin location algorithms are based on Nonlinear Regression (NLR) schemes using Simplex search engines. To improve location 3-8 hits are used (Over-determined Method) versus just 3-hits for a common arbitrary placement presently used in the AE industry. To further improve the AE source accuracy and intensity distance amplitude correction plots are introduced where the AE user develops an attenuation profile for the appropriate threshold settings that determine AE source sensitivity.
