2290 Precision Reference Module
The 2290 is a single-axis precision reference calibration module that can be used to accurately determine the sensitivity and frequency response characteristics of unknown MEMS DC accelerometers. Based around SDI's 1527 tactical-grade model, it is ideal for calibration and performance specification comparisons, and can also serve as a working accelerometer in its own right.
The low-SWaP unit features a rugged and epoxy-sealed anodized aluminium enclosure with a 1-inch square footprint, and provides a convenient 4-wire pigtail on an integrated 10” cable for easy compatibility with almost any DAQ system.
