FUNCTIONAL DESCRIPTION
The 104-AIO16-16E is an economical 16-bit resolution board which provides speeds up to 250kHz for 16 single-ended or 8 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-AIO16-16E 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 250kHz sampling rate is supported by a 2K-sample data FIFO (optional, up to 32K 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-AIO16-16E 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.
