Description

The PCI-9118 Series is a family of high performance data acquisition boards for PCI-based PC. All member of this family share a common architecture and core features. It is ideal DAQ card for high speed,gap-free data acquisition applications.

Channel/Gain Queue high speed scanning
A 256 location channel/gain queue on the PCI-9118 Series allows high speed acquisition with channels at different gains and in non-sequential order using bus-mastering DMA and FIFO interrupt based data transfer.

Continuous gap-free, high performance under Windows
The onboard 1024 locations of FIFO ensure that high-speed data acquisition can be maintained reliably under Win-3.11, Win-95, and Win-NT. The data can
be transferred through bus mastering DMA (PCI feature) which results in continuous gap-free, high throughput, even for large amounts of data.
