1. Pattern generation rates depend on your computer, software, and other bus activity. The rates shown were
measured for 100 kS transfers on sample Intel Pentium-based computers, using NI-DAQ software, with no other
DAQ operations in progress. The PCI-DIO-32HS Triton I rates were measured on a 100 MHz Pentium computer with
the Triton I (430FX) chip set. The PCI-DIO-32HS Triton II rates were measured on a 166 MHz Pentium computer
with the Triton II HX (430HX) chip set. The PCI-DIO-32HS Natoma rates were measured on a 180 MHz Pentium
Pro system with the Natoma (440FX) chip set. The PXI-6533 rates were measured using a 133MHz Pentium
CompactPCI controller with the Triton I chip set. The AT-DIO-32HS rates were measured using the dual-DMA
transfer method on a 100 MHz Pentium computer with the Triton I (430FX) chip set. The DAQCard-6533 Triton I
rates were measured using a 75 MHz Pentium computer with the Triton I (430FX) chip set. The DAQCard-6533
Triton II rates were measured using a 133 MHz Pentium computer with the Natoma (430HX) chip set. The
DAQCard-6533 266 MHz Pentium II rates were measured using a 266 MHz Pentium II computer with the Natoma
(440FX) chip set.
