A Multisinusprüfung is a test signal method where (sinusoidal oscillations) of different frequencies, amplitudes, and phases are summed together and applied to a Device Under Test (DUT) simultaneously. Unlike a single sine sweep (which tests one frequency at a time) or white noise (random signal), a multi-sine is deterministic and periodic.
: 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: multisinusprüfung
: It provides much higher resolution exactly where the product is most likely to fail (at its natural frequencies). A Multisinusprüfung is a test signal method where
If you need a definition block:
Here is the detailed content regarding what it is, how it works, and where it is applied. It ensures the test stays "fatigue-equivalent" even as
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).
