The USB-6211 is a multifunction DAQ device. It offers analogue I/O, digital input, digital output, and two 32-bit counters. The device provides an on-board amplifier designed for fast settling times at high scanning rates. It also features signal streaming technology that gives you DMA-like bidirectional high-speed streaming of data across USB. The device is ideal for test, control, and design applications including portable data logging, field monitoring, embedded OEM, in-vehicle data acquisition, and academic. The USB-6211 features a lightweight mechanical enclosure and is bus powered for easy portability. The included NI-DAQmx driver and configuration utility simplify configuration and measurements.
Note Accuracies listed are valid for up to one year from the device external calibration.
Note The input/output channels of this device are not protected for electromagnetic interference due to functional reasons. As a result, this device may experience reduced measurement accuracy or other temporary performance degradation when connected cables are routed in an environment with radiated or conducted radio frequency electromagnetic interference. To ensure that this device functions within specifications in its operational electromagnetic environment and to limit radiated emissions, care should be taken in the selection, design, and installation of measurement probes and cables.
