New add-ons for the QC Software Framework

New add-ons available

Klippel now provides a new add-on for the Sound Pressure Task of the KLIPPEL QC Framework. The Hi-2 Weighted Harmonic Distortion (Hi-2) is calculated from higher order harmonic distortion. Such harmonics are weighted in a special way to emphasize defect symptoms of unacceptable speaker behavior. The SPL Task uses a sine chirp for Hi-2 distortion measurement and can therefore measure this symptom in a very short time. Hi-2 distortion may also be measured by our DIS Pro module using steady state sine tones.

The optional Hi-2 module covers the following features and benefits:

  • Fast measurement of Hi2 distortion (also called “BLAT“)
  • Using sine chirp
  • Standardized or user defined limits
  • Conform to automotive standard
  • Sensitive distortion measurement of higher harmonics.
The new technical documents are now available on the KLIPPEL website

In addition, the new T/S Parameter Laser Fitting (TSX) is an add-on for our Impedance Task (IMP) of the QC software framework that enhances the impedance-based lumped parameter fitting of the IMP with state-of-the-art laser displacement measurement. This yields the complete set of linear transducer model parameters including force factor Bl, moving mass Mms as well as mechanical stiffness Kms and losses Rms for full production supervision, process control and root cause analysis.

Based on dedicated stimuli and advanced fitting algorithms including suspension creep, the TSX determines accurate transducer parameters within fractions of a second in one step. More information for further features and benefits can be found on the KLIPPEL website
