CLIO electroacoustic instrument
Clio electroacoustic instrument with extraordinary economic price established electroacoustic testing system performance to price the new standard, which is compatible with the currently analysis of MLS&Logchirp electroacoustic testing system used, sinasoical scanning, FFT, and up to 12 functions in a body, is simple and friendly interface, and fast measurement data and graphic import export functions is to meet the needs of your current and future audio test, excellent performance, applicable in a wide range of electroacoustic instrument.
Function IntroductionTechnical ParametersConfiguration Checklist

With the software system for CLIO11 Clio is a complete audio and acoustic testing apparatus and make the state of theart solutions of laboratory, field and production quality control applications.CLIO11 is designed to support and drive the existing hardware, such as the fw01 audio interface and ready to adapt to the future development; support for the operating system has been extended to the latest Windows 8.

This paper briefly introduces some new features that are given CLIO11:

CLIO11 firewall is a system.It includes the fw01 interface hardware and it runs CLIO11 standard software or QC CLIO11.These two parts can not be alone.

The fw01 live wire audio interface sets the new hardware accuracy standards for the test system.

CLIO 11 software is a new measurement software for CLIO system..CLIO11 software is fully compatible with XP, Vista, Windows 7 and 8.

Software Testing Technology

Compared to other measurement systems, CLIO11 concentrates many different audio power to a single.

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

The analysis of the stimulus by the US and logchirp using pseudo random noise or logarithmic pulse

Sinusoidal sweep using sinusoidal signal

FFT, RTA and "live" transfer function lets you choose any stimulus, or even live music.While other instruments offer a possible measurement option, CLIO11 gives you three options that allow viewing of physical phenomena like frequency response, impedance or other parameters from three different perspectives.The final results will be verified by the consistency of these measurements: any expert technicians who know that this is the right approach should be used.

The following professional control panel for other specific measurements:

Sound level meter iec61672 integral sound level meter and frequency analysis Leq

The nonlinear distortion of an electronic device is nonlinear behavior

Interactive LCR bridge allows the passive components to measure the fly

The time and frequency of the robot

Frequency counter

In addition to measurement results you get a sophisticated post-processing tool:

Characteristic parameters of Thiele speaker

Characterization of the acoustic parameters of IS3382 and STI and the hall of the room

The waterfall graph to evaluate the sound attenuation of 3D or color plots

The directivity of the speaker is characterized by color maps, circular or waterfall like scenarios

Complete 3D speaker directivity characterization of three-dimensional balloon analysis (only in the QC version)

Wavelet analysis of the characteristics of joint time-frequency speakers

Evaluation of RLR loudness rating calculator, SLR and masking (only in QC)

Use all of the above measurement and post processing techniques, it is powerful quality that can be customized script control, the management and identification of electronic or electro acoustic device production line.

(*) only 32 bit operating systems

The quality control for the CLIO software extension is performed by the art production line test state: a robust suite.

CliOQC implements all the measurement techniques in the standard software of the European standard to add a generic script processor to the discovery of the test sequences that best suit your needs.

CliOQC can test a loudspeaker, production driver, microphone, amplifier and other electroacoustic devices.

CliOQC can interact with the external hardware or the production line controller in addition to the PC peripheral, the computer network or the custom software to realize the automatic test line..

CliOQC can be configured as a test server.It can easily be a system for complex quality measurement techniques in a custom written application.In the interaction occurring with the TCP / IP transmission protocol gives the possibility of remote control for network.ompared other measurement systems, and CLIO11 focuses on the power of many different musical instruments to a single.
