Multi-Tone Measurement (MTON)

Features and Benefits

  • Multi-tone fundamental and distortion measurements
  • SPL Max and max. voltage according to IEC 60268-21
  • Continuous maximum SPL related to ANSI/CEA-2010-B, ANSI/CEA-2034
  • Thermal compression
  • Variable measurement and cooling time durations
  • Measurement of wireless, active and passive speakers
  • Get acoustic “Fingerprint”
  • Flexibility on stimulus and threshold setup
  • Protection limits to avoid the DUT destruction
  • Temperature protection

The MTON Multi-tone Measurement is a Klippel RnD module which provides a complete measurement of the device under test (DUT) using a multi-tone stimulus. MTON module offers different measurement modes to provide a high flexibility of measurement procedures.

While the Single Measurement mode performs a single multi-tone measurement, the Multiple Measurements: Voltage Increase mode offers an automatic test sequence to obtain the operation limits of the DUT related to mechanical and thermal compression as well as multi-tone distortion.
This flexibility in the threshold and stimulus configuration allows the MTON module to pinpoint the SPLmax according to IEC 60268-21 as well as the continuous max SPL (ANSI/CEA-2010-B and ANSI/CEA-2034) among other standard measurements.
