Abstract
A calibration unit, system, and method for calibrating a device under test are provided. The calibration unit, system, and method use a single axis rotational unit to calibrate devices under test on a test head. The single axis rotation unit is configured to extend at an angle from a known axis. The test head can be designed in the shape of a frustum with multiple sides. The calibration unit, system, and method can use combinations of gravitational excitation, Helmholtz coil excitation, and rotational rate excitation for calibrating the device under test. The calibration unit, system, and method can calibrate a 3 degree for freedom or higher MEMS devices.
