FUNCTIONAL DESCRIPTION
The 104-AIO16-16W is a high-speed, 16-bit resolution board which provides speeds up to 500kHz for 16 single-ended or eight true differential analog input channels. This multifunction board features an excellent price/performance value for precision PC/104-based data acquisition, control, or signal analysis of standalone environmental test stations, compact production test equipment, portable testers, avionics and other applications.
The 104-AIO16-16W features 11 standard analog input ranges and a filtered, extremely quiet front end. The module also offers on-board hardware oversampling for additional noise reduction. In addition to direct data transfers, the board’s ability to trigger the A/D in real time assures synchronized sampling that is unaffected by other computer operations—an essential requirement for signal, vibration and transient analysis where high data rates must be sustained for short periods of time. The 500kHz sampling rate is supported by a 1024-sample FIFO (optional, 2, 4, 32, and 64K samples) for reducing processor overhead. Sixteen parallel bits of digital I/O and two 12-bit D/A outputs allow for a complete, high-performance data acquisition solution.
SOFTWARE
The 104-AIO16-16W is supported for use in most operating systems and includes a free DOS, Linux and Windows 95/98/Me/NT/ 2000/XP/2003 compatible software package. This contains sample programs and source code in "C" and Pascal for DOS, and Visual Basic, Delphi, C++ Builder, and Visual C++ for Windows. Also included is a graphical setup program in Windows. Linux support includes installation files and basic samples for programming from any user level via an open source kernel driver.
