Sensitive Rub & Buzz Testing
The KLIPPEL QC system offers outstanding sensitivity for all kinds of irregular distortion caused by mechanical defects. Such defects are easily audible by end users, badly affecting the audio quality. Thus they need to be detected as early as possible. High-order distortion is analyzed in the time domain by exploiting full spectral amplitude and phase information to detect even the tiniest impulses from loose particles, which may be 80 dB below the main signal level. Even if such defects are hardly audible at the component test, they should not be ignored since they might become worse in the final application.
- Avoid shipping defective units
- Very high sensitivity
- Detects rubbing, buzzing, loose particles
- Transient high-order distortion analysis
- Excite all defects by sine sweep
