A New QC Module - Multi-Tone Distortion
New module: MTD
In order to provide dedicated tools for standard-compliant audio testing, KLIPPEL released a new software module: QC Multi-tone Distortion (MTD) for efficient end-of-line testing. The Multi-Tone Distortion Task (MTD) is an add-on for our QC software framework that can be inserted as a test step (task) in any existing QC test. It ensures overall consistency of production electrically and acoustically.
The MTD task covers the following features and benefits:
- Multi-tone stimulus
- „Fingerprint“ testing of speakers and audio systems
- Stimulating harmonics and intermodulation distortion
