    Abstract: Methods and systems of testing microelectromechanical (MEMS) devices are disclosed. A method includes mechanically coupling a wafer including MEMS devices to a test system and electrically coupling one of the MEMS devices through a probe card to a pulse measure unit (PMU) of the test system. The method includes driving, through the PMU, drive nodes of the MEMS device with an applied time-varying electrical signal to cause a resonance condition of the MEMS device, and sensing, through the PMU, an electrical signal generated across sense nodes of the MEMS device responsive to the resonance condition. A resonance frequency and quality factor of the MEMS device are determined based on the sensed electrical signals across the sense nodes of the MEMS device, and whether the MEMS device passes a quality factor test is made based on the calculated quality factor.
