1. Handshaking rates depend on your computer, software, other bus activity, and handshaking protocol. The rates

shown were measured using NI-DAQ software and the burst-mode handshaking protocol, performing continuous

waveform generation using 100,000-point or larger buffers, with no other DAQ operations in progress. The PCI-

DIO-32HS, PXI-6533, and AT-DIO-32HS handshaking rates are DMA-based and do not necessar ily in creas e as the

speed of the computer increases. The PCI-DIO-32HS and AT-DIO-32HS rates shown were measured on a sample

100MHz Intel Pentium-based computer with an Intel 430FX (Triton I) chip set. The PXI-6533 rates were measured

using a 133MHz Pentium CompactPCI controller with a Triton I chip set. The DAQCard-6533 rates do tend to

increase as the speed of the computer increases. The DAQCard-6533 75MHz Pentium rates were measured using a

75MHz Pentium computer with the Triton I (430FX) chip set. The DAQCard-6533 133 MHz Pentium rates were

measured using a 133MHz Pentium computer with the Natoma (430HX) chip set. The DAQCard-6533 266 M Hz

Pentium II rates were measured using a 266MHz Pentium II computer with the Natoma (440FX) chip set.
