Microstar Laboratories has introduced a significant upgrade to its specialised 8-channel, 16-bit resolution PCI DAP board, the IDSC 1816.
The board can now sample at precisely 102,400 samples/second simultaneously on each channel, an ideal rate for 1024-point FFTs binning at 100Hz.
The IDSC 1816 applies first stage analogue filters, and combines the best analogue techniques before signal conversion with user-selectable digital filter algorithms applied after A-D conversion.
The algorithms run on dual 80MHz digital signal processors controlled by a general purpose 32-bit processor and supported by 16 MB of memory.
The board can acquire data at up to 153.6ksamples/second per channel (the rate for 1024-point FFTs binning at 150Hz), and filters signals for all forms of spectral analysis.
The IDSC 1816 is controlled from any Windows NT or 9x system that contains the board, and it can also be controlled remotely over a network.
The IDSC 1816 features data acquisition with 16-bit resolution, optical isolation, and anti-aliasing, 8 inputs with simultaneous sampling, independent onboard filters with flat passbands, linear phase and steep roll-off, wide-ranging cut-off frequencies up to 61.44kHz selectable by channel and expansion to 112 simultaneous channels in one PC.
These features bring to PC-based systems the virtual brick-wall filters needed for critical results in spectral analysis applications such as sonar and monitoring vibrating and rotating assemblies in the automotive, aerospace, and power generation industries that require high accuracy over several channels.
The DSCview for Windows software included with each board enables the shape of the response curve for each filter to be changed; the filter can then be attached to one or more channels, or a different filter can be constructed for each channel.
A demo version of this software is available from www.mstarlabs.com/ftp/webftp.html.
The board also comes with support for programming languages and for common data acquisition applications such as Labview, HP VEE, Dasylab, Diadem and Matlab.
