Impedance Task (IMP)

Task of the QC STANDARD Software and Optional Module for the R&D System

Features and Benefits

  • Measurement module for the Klippel Analyzer System
  • Optimized for quality control applications, such as end-of-line testing
  • Included in the Klippel QC Standard Software package
  • Stimulus: fast multi-tone or chirp based
  • Inductance models: Wright, Leach, LR-2
  • Electrical signal (voltage, current) analysis providing

    • T/S parameter identification according to IEC 60286
    • Vented Box Parameters (fb, Qb)
    • Impedance amplitude and phase frequency response
    • Current and voltage spectrum, noise and distortion
    • Limits and grades for all measures
    • Online yield, process control Cpk/Ppk, control rules 

The Impedance Task (IMP) identifies the lumped parameters of the equivalent circuit of the transducer, including Thiele/Small, creep and lossy inductance parameters. It complies with IEC standards 60268-5 and 60268-22. A multi-tone stimulus is used to measure the voltage and current using the measurement hardware Klippel Analyzer KA3 (QC Card, Speaker Card) or Production Analyzer. To ensure accurate measurement in the small signal domain, distortion in current and voltage are measured and checked against admissible limits.
