Noise and Vibration Analyzer

LMS Test.Xpress ——Integrated platform for noise, vibration and durability

Traditional analyzers are extremely flexible tools to qualify products’ noise, vibration or durability performances. They are easy to operate and immediately show the frequency content of a vibration, sound or fatigue signal. They are, however, also very limited. Why restrict measurements to just 2 or 4 channels, when productivity could be so much higher with 8 channels or more? What about direct ...

LMS Test.Xpress, Integrated acquisition and analysis capabilities

Single sheet user interface All functions and parameters at your fingertips Direct response to parameter changes Designed for optimal productivity Real time power FFT, order, octave and throughput in parallel and in real-time Online visualization of all functions Diagnose problems while you measure Short learning curve Connect your system and start measuring Interactive and intuitive screen layout Ease of use and power in one system Guided operator use Toolbar guides user ...

LMS SCADAS Mobile, power and flexibility for lab and field testing

LMS Test.Xpress is seamlessly integrated with the state-of-the-art LMS SCADAS Mobile and LMS SCADAS Recorder front-ends. The LMS SCADAS Mobile is one of the most powerful, compact and lightweight data acquisition front-ends of its class, bundled into a fully rugged and ultra-portable front-end package. Built on LMS SCADAS Mobile technology, the LMS SCADAS Recorder can be used as an autonomous recorder, as a smart recorder with a wireless PDA connection or as a front-end system for in-field and ...

Octave analyzer

The LMS Test.Xpress Octave Analyzer is ideal to troubleshoot acoustic problems. The octave filter functions can be averaged or tracked against a specific channel.To perform various analyses simultaneously, combine the octave analysis with any other analyzer function. The LMS SCADAS front-end has no cooling fan and provides the silent operation required for acoustic testing. ...

Integrating sound level meter

The LMS Test.Xpress Octave Analyzer also replaces traditional integrating sound level meters. It supports the full set of sound level meter functions while providing calculation on multiple channels, granting users full insight in the data with just one measurement. ...

Durability analyzer

The LMS Test.Xpress Rainflow and Histogram Analyzer supports in-depth analysis for durability and fatigue. Single value statistics such as maximum, minimum, mean or standard deviations are calculated on streaming channels.Detailed durability analysis includes pectral analysis, Rosette calculations, rainflow counting, range-pair counting and time-at-level calculations, for easy determination of fatigue behavior in different loading conditions. Video images can be added and compared to measured ...

ISO human body vibration

The LMS Test.Xpress Human Body Vibration is a powerful certification tool for ISO 2631 and ISO 5349 standards. The color-coded 2D display gives real-time feedback and clearly indicates limit values and/or violations as specified in the EC directives. In-depth root causeanalysis of non-compliant results is obtainable. ...

ISO sound power

ISO certification testing is made easy with LMS Test. Xpress. To ensure compliance with the ISO measurement process and minimize operator error, the complete procedure is fully automated and protected by a userdefined password. The resulting report in MS Excel and/or Word contains all ISO required information. ...

ISO sound intensity and source localization

LMS Test.Xpress optimally supports sound intensity-based ISO certification tests for both point and scanning methods. Critical results such as ISO field indicators (F1, F2, F3 and F4), calculated levels (sound power, sound intensity and pressure intensity) are presented in tabular format. Corrective actions are suggested if the ISO criteria are not met....

Modal impact testing

LMS Test.Xpress Modal Impact Testing supports interactive and easy measurement using impact hammer excitation according to “roving” or “fixed hammer” techniques. The calibration wizard guides the user through the calibration process. Calibrator, channel information and data visualization in time and frequency domains are clearly displayed. Impact hammer trigger detection is fully automated through trigger detection wizard. ...

What’s new in LMS Test.Xpress Revision 4

In LMS Test.Xpress Revision 4, the new noise and vibration analyzer delivers a newly integrated sound level meter, a new ISO 3747sound power standard for in-situ measurements and a triggered intensity functionality that assesses synchronous sound intensity even in noisy environments. Revision 4B of the LMS Test.Xpress software has been released in July 2010. Durability testing engineers will welcome the improved strain gauges and durability sensors support that includes fast balancing, intuitively ...

LMS Test.Xpress Revision 3A Sound Power & Sound Intensity

Easy ISO certification and acoustic troubleshootingSupporting ISO standards is nothing new for LMS Test.Xpress. The previous version already supported pressure-based sound power measurements based on the ISO standards: ISO3741, ISO3742, ISO3743, ISO3744, ISO3745 and ISO3746. This new version does the work for you. It automates the formerly cumbersome ISO process associated with so-called “declared sound power” certification and adds additional support for ISO9614 sound power requirements ...
