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).

Here is the detailed content regarding what it is, how it works, and where it is applied. multisinusprüfung

In a German automotive lab (e.g., testing an engine mount): If all phases are zero, the sine waves

: 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
