MEASUREMENT TECHNIQUES

Compared to other measurement systems, CLIO concentrates the power of many different instruments into a single one.

Three different measurement techniques are available for system identification and characterization:

MLS & LogChirp analysis using either pseudorandom noise or logarithmic chirps as stimuli

Sinusoidal Sweeps using sinusoidal signals

FFT, RTA and ‘Live’ Transfer Function letting you the choice of any stimulus, even music.

While other instruments offer one single possible measurement choice, CLIO permits you to view the physical phenomenon like frequency response, impedance or other parameters, from different points of view. The final result will be then validated by the consistency of these measurements: as any expert technician knows, this is the correct approach that should always be adopted.

The following specialized control panels are dedicated to other specific measurements:

• Linearity and Distortion measures the non linear behavior of an electronic equipment
• Sound Level Meter a IEC61672 integrating sound level meter with Leq and frequency analysis
• Interactive L-C-R Bridge permits passive components measurement on the fly
• Wow&Flutter Meter with time and frequency analysis
• Frequency Counter
• Direct STIPA rating

Beyond measured results you get sophisticated post-processing tools for:

• Thiele&Small Parameters for loudspeaker characterization
• ISO 3382 Acoustical Parameters, indirect STI and STIPA for rooms and auditoria characterization
• Directivity analysis for loudspeaker as 2D Color maps, Circular or waterfall-like plots or 3-D Balloons analysis (only in QC version) for complete spatial characterization
• Time-Frequency Analysis to evaluate Cumulative Spectral Decays, Energy Time Frequency, Wavelet Analysis and Cycle Wavelet Analysis. Either as 3D plots or Color Maps.
• Loudness Rating Calculator for assessing RLR, SLR and STMR (only in QC version)

Using all the aforementioned measuring and post-processing techniques it is possible to tailor powerful Quality Control scripts that will manage and identify any production line of electronic or electro-acoustic devices.
