This multifunctional screening system is developed by using the characteristics of spectral control and spectral responses. It exhibits the power of close loop spectral control of Electromagnetic shakers, including other capabilities of resonance sorting and control, and is used to precisely detect design defects and extremes of the screened products.

During the screening stage of products under mass production, this system exhibits its on-site capability in the production lines. Along with proper automatic fixtures, setting up relative screening vibration levels and vibration spectrum in accordance with product's operational extremes obtained and identified during the research stage, screening purpose can be quickly reached and screening effects can thus be ensured.
