PCI Express speeds data acquisition

With high-speed, highvolume industrialautomation, laboratory- measurement, actuatorcontrol, and acoustic applications in mind, Adlink Technology recently unveiled a line of PCIe (PCI Express) data-acquisition cards. With a choice of input ranges and sampling speeds plus a differential mode to maximize noise suppression, the DAQe-2200 series samples as many as 64 analog channels with a maximum data-transfer rate of 250 Mbytes/sec over the one-lane PCIe bus. The DAQe-2200 series comprises the 12-bit DAQe-2204 ADC card with a 3M-sample/ sec sampling rate; the 16-bit DAQe-2205 ADC card with a 500k-sample/sec sampling rate; and the 16-bit DAQe-2206 ADC card with a 250k-sample/sec samplingrate.

The cards include analog and digital triggering, two 12-bit analog outputs, 24 programmable digital-I/O lines, and two 16-bit timer/counters. The DAQe-2200 series also features a system-interface bus to allow the synchronization of as many as four cards, autocalibration that adjusts gain and offset, and high-speed transfer of data directly to and from memory through the DMA controller. The DAQe-2200 series of cards has prices starting at $895, with volume discountsavailable.
