Feature Concept: Resonance-Aware Adaptive Sweep Partitioning

: It could potentially cut another 20–30% off the already-reduced multi-sine test time by not wasting energy on "non-resonant" frequency gaps. Multi-sine Vibration Testing - Crystal Instruments multisinusprüfung

Moderne Schwingungsregelsysteme ermöglichen es, bis zu simultan zu steuern. Jeder dieser Töne kann über eigene Amplituden und Sweep-Raten verfügen, was eine präzise Nachbildung komplexer Betriebszustände erlaubt. Die zwei Haupttypen der Multisinus-Anregung To protect the DUT and amplifier, engineers use

: For durability testing, the feature could automatically adjust the amplitude of specific tones if it detects that a certain resonance is "drifting" (a sign of material fatigue or structural softening). It ensures the test stays "fatigue-equivalent" even as the test object's properties change. Why this is a "killer" feature:

If all phases are zero, the sine waves align at $t=0$ to create a massive voltage/amplitude spike. To protect the DUT and amplifier, engineers use Schröder phases or iterative algorithms to flatten the time-domain signal (reduce the Crest Factor to ~1.6–2).

The excitation signal is defined mathematically as: $$x(t) = \sum_k=1^N A_k \cdot \sin(2\pi f_k t + \phi_k)$$
