摘要: An apparatus and method is provided for testing performance characteristics of a MEMs device. The includes test probe that electrically connected to mechanical member the device receiving electrical data signals from are indicative movement due external excitation. also communications means transmitting probed an analyzer analyzing determine amplifier between communication means. placed in close proximity such it amplifies prior transmission by As such, amplified before sufficient noise introduced into reduce their signal ratio less than predetermine level. By amplifying introduction significant noise, signals, which may have relatively small amplitude, not obscured noise.
