MIMO Shock Response Spectrum (SRS) Control

The MIMO Shock Response Spectrum (SRS) control package provides controls of multiple shakers to meet multiple target Required Response Spectrum (RRS). Time waveforms are automatically synthesized from a user-specified SRS reference profile using different types of wavelets. Sine beats and damped sine are commonly used types of wavelets. Each control channel is assigned with one RRS and to the synthesized time waveform accordingly. Users can apply high frequency waveforms and alarm and abort tolerances to any active channel to provide an extra degree of safety for delicate test articles.
