National Instruments Introduces 16 New X Series Data Acquisition Devices for PCI Express and PXI Express

Aug. 5, 2009 – National Instruments has announced X Series multifunction data acquisition (DAQ) devices for PCI Express and PXI Express. The 16 new X Series DAQ devices provide enhancements to analogue I/O, digital I/O, onboard counters and multidevice synchronisation. X Series devices integrate native PCI Express support for high-throughput data transfer, advanced timing and synchronisation technology for precise measurement and control and the ability to perform advanced processing and analysis on today’s multicore systems.

X Series DAQ devices, which include up to 32 analogue inputs (AI), four analogue outputs (AO), 48 digital I/O lines and four counters, range from low-cost 250 kS/s multiplexed AI to 2 MS/s simultaneous sampling AI. Simultaneous X Series devices integrate up to 16 ADCs on a single device at 2 MS/s per channel, so engineers can sample all AI channels at a high rate and with minimal phase offset. With high sampling on all channels, simultaneous X Series devices pass large quantities of data back to the host PC, delivering a total AI throughput of up to 64 MB/s. With the added throughput of AO, digital I/O and counter operations, total throughput can surpass 100 MB/s for a single device – the practical maximum of the PCI bus. For this reason, X Series devices use the high-throughput PCI Express bus.
