64-Channel Data-Acquisition Cards Feature High Data Rates

The DAQe-2200 series from Adlink Technology use the x1 PCI Express bus to allow simultaneous 12-bit, 3-Msample/s data acquisition on 64 channels.

A family of three high-performance, multi-function, 64-channel data-acquisition cards take advantage of the high-bandwidth of the x1 PCI Express bus for data transfers of up to 250 Mbytes/s. The DAQe-2200 series from Adlink Technology Inc. consists of the DAQe-2204, a 12-bit analog-to-digital resolution card with a 3-Msample/s simultaneous sampling rate; the DAQe-2205, a 16-bit resolution card with a 500-ksample/s simultaneous rate, and the DAQe-2206, a 16-bit resolution card with a 250-ksample/s simultaneous rate. The 64 analog channels feature various input ranges to 10 V. A differential mode for 32 analog channels maximizes noise reduction.

The cards include analog and digital triggering, two 12-bit analog output channels with waveform generation, 24 programmable digital I/O lines, and two 16-bit general-purpose timer/counters. The DAQe-2200 series also features simultaneous analog input and output at full speed, a system synchronization interface bus that allows up to four cards to be synchronized, auto-calibration that adjusts the gain and offset to within specified parameters, and scatter-gather bus mastering. The latter allows the acquisition of a large amount of data at a high speed by transferring data directly to and from memory through the DMA controller (up to the size limited by the system memory).
