Multi-Tone Measurement (MTON)
Features and Benefits
- Multi-tone fundamental and distortion measurements
- SPLmax and max. voltage according to IEC 60268-21
- Continuous maximum SPL related to ANSI/CEA-2010-B and 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 R&D module which provides a complete measurement of the device under test (DUT) using a multi-tone stimulus. MTON 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 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 [1] as well as the continuous max SPL (ANSI/CEA-2010-B [2] and ANSI/CEA-2034 [3]) among other standard measurements.

Demo Video
Multi-Tone Measurement - MTON & QC MTD
The tutorial shows an overview of the principle of multi-tone measurement and it introduces our sister modules for R&D applications (MTON module) and End-of-Line testing (MTD task). It shows practical demonstrations for typical measurements and that all distortions (HD, IMD, Rub&Buzz) are available by a single measurement.
