The DSKTOP6 is a complete, very high performance data acquisition system. The DSKTOP6 includes a high speed, windows optimized high resolution data acquisition board, cable, terminal panel and WINview software.

The PCI-PD2-MF-16-2M/14H data acquisition board has 8 differential analog inputs (or 16 singled ended). These inputs are multiplexed to a 14 bit A/D converter with a maximum throughput of 2.2 MHz. The PCI-PD2-MF Series data acquisition boards are PCI "Bus Masters" acheiving optimum performance without the need for the computer's interrupts or DMA channels. The data acquisition boards also have 32 lines of TTL level digital I/O, 16 digital TTL inputs (8 can generate interrupts on change of state) and 16 digital TTL outputs. The PCI-PD2-MF Series data acquisition boards also feature two 12-Bit Waveform Quality D/A voltage outputs with 2K FIFO support. Three 16-bit counter/timers are available to the user, while onboard pacer clocks perform both A/D and D/A functions. All subsystems run simultanously under the control of a Motorola 66 MHz DSP chip. The board connections are terminated in a 100 pin connector at the rear of the PC.

The boards' extensive software support includes Windows 95/98/ME/2000/XP drivers for Visual Basic, Visual C++, Delphi, TestPoint, LabVIEW, WINview Series Software, DASYLab, MATLAB DAQ Toolbox...Plus support for Linux, RTLinux, QNX.

WINview software is included. WINview is easy-to-use, yet very customizable and arrives ready-to-run with the PCI-PD2-MF-16-2M/14H (see WINview specifications for more details on WINview).
