PCI Express DAQ Modules Expand Throughput

Announced as the industry’s first data-acquisition (DAQ) modules for PXI Express, the PXIe-6259 and PXIe-6251 M Series modules deliver analog and digital I/O at rates up to 250 MB/s per-slot. The modules feature up to 32 analog channels with a 16-bit sampling speed of 1.25 Msamples/s. Up to four 16-bit analog output channels are available with 2.8-Msample/s update rates as well as 10-MHz digital I/O on up to 32 lines. Similar to existing M Series modules, the PXIe-6259 and PXIe-6251 employ a NI-STC 2 system controller, NI-PGIA 2 amplifier, and NI-MCal calibration technology. Additionally, they support code written for LabVIEW, LabWindows/CVI ANSI C, and Measurement Studio. NATIONAL INSTRUMENTS, Austin, TX. (888) 280-7645.
