Abstract：From the viewpoint of signal and system, high-speed seismic waves shot by dynamite offer a very coincident input to the system designed speci-fically, an array of sensors spaced approximate 20 cm and located within an area of 1m×1m. Diffe-rent outputs characterize different properties of the sensors. By analyzing the output data, some parameters of the sensors, such as sensitivity, ultra-low-frequency distortion and tolerance, could be evaluated. This paper describes the basic principles and practical application of the above idea, and proposes two new concepts (Lowest Faithful Frequency and General Consistency) to analyze the recording ability for low-frequency and general reliability of some sensors, both of which are significant to imaging subsurface media, and concludes that the performance of the sensors is more quantified and complete. The method, termed Micro Box Wave Test, can be applied in two scenarios:to quickly find unqualified sensors before large-scale field acquisition, and to calibrate the parameters of new sensors in field.
