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

Gap-free/high performance in Windows Applications.
The onboard 1024 locations of FIFO ensures the high-speed data acquisition can be maintained reliably
under Win-3.11, Win-95, and Win-NT. The data canbe transferred through bus mastering DMA (PCI
feature) and meet gap-free, high throughput of continuous, even for large amount of data.
