Spectrum Analysis (SAN)
Task of the QC STANDARD Software and Optional Module for the KLIPPEL QC Framework
- Spectrum analysis of any noise source
- A-weighted sound pressure level
- Frequency response with noise (white, pink) or any other test signal (e.g. music)
- Incoherence analysis provides distortion assessment
- Phase and polarity
- Simple, universal, flexible
- Use your favorite test signal
- Noise & vibration testing
The Spectrum Analysis (SAN) is a versatile tool for the QC framework of the KLIPPEL Analyzer System dedicated to testing loudspeakers, audio systems or any sound emitting devices with no signal input. A white or pink noise generator is provided to measure characteristics like sound pressure spectrum, frequency response, A-weighted level and incoherence. You may use your own stimulus signal that can be imported as a wave file. Even when no test signal can be applied, you may evaluate the spectrum and level of any sound or noise sources and apply PASS/FAIL limits. The SAN is included in QC Standard Software and is available as a module for R&D applications. For dedicated noise and vibration testing, it is also available in QC Basic (Special Application) version.
