Adlink's PCIe DAQ cards

Adlink Technology Inc. introduces the DAQe-2200 series of high-performance multifunctional DAQ cards that take advantage of the high-bandwidth benefit of the x1 PCIe bus for large-scale data transfers of up to 500MBps.

The DAQe-2200 series samples up to 64 analog channels with various input ranges (up to 10V) and sampling speeds (up to 3MSPS) while offering a differential mode for 32 analog channels to maximum noise elimination. This series features analog and digital triggering, 2-CH 12bit analog outputs with waveform generation, 24CH programmable digital I/O lines and a 2-CH 16bit general-purpose timer/counterideal for high-speed high-volume data acquisition in industrial and laboratory measurement/automation, actuator control, ultrasonic and acoustic applications.

The DAQe-2200 series consists of the DAQe-2204, a 12bit A/D resolution card with a 3MSPS simultaneous-sampling rate, the DAQe-2205, a 16bit A/D resolution card with a 500KSPS simultaneous-sampling rate and the DAQe-2206, a 16bit A/D resolution card with a 250KSPS simultaneous-sampling rate.

The DAQe-2200 series also features simultaneous analog I/O at full speed, a system synchronization interface bus to allow 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 scatter-gather bus-mastering feature 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.
