FUNCTIONAL DESCRIPTION

The high-speed Model LPCI-A16-16A provides 500k samples/second, with 16-bit resolution, for the board's 16 single-ended or eight differential analog input channels. Also included are two 12-bit analog outputs, 16 digital I/O lines and an 8254 with three 16-bit counter/timers. The board meets the MD2 Low Profile PCI Bus Specification and can be installed in any 3.3V or 5V PCI or PCI-X slot. This multifunction I/O board is useful where space is limited such as thin-client and high-density rack-mount servers and many embedded applications. Priced at just $695, the board features an excellent price/performance value for precision PC-based measurement, analysis, monitoring and control.

The LPCI-A16-16A features 11 standard analog input ranges and an extremely quiet front end. A unique channel-by-channel programmable gain feature enables measurement of an assortment of large and small signals in one scan all under hardware control at over 400k samples/second. The board's data FIFO and 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. Connections are made to the board via a 50 pin SCSI connector. A shielded round wire cable model and screw terminal board are optionally available as accessories for bench testing or as part of an overall OEM solution.

SOFTWARE

The LPCI-A16-16A is supported for use in all operating systems and includes a free DOS, Linux and Windows 95/98/Me/NT/2000/2003/XP compatible software package. This includes 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 user level via an open source kernel driver.
