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 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 most operating systems and includes a DOS, Linux, and Windows 95/98/Me/NT/ 2000/2003/XP 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 incorporated is a graphical setup program in Windows. Third party support includes a Windows standard dll interface usable from the most popular application programs, along with LabView .VI samples. Linux support consists of installation files and basic samples for programming from user level via an open source kernel driver.
