LMS Sound & Vibration Testing Solutions

LMS Test.Lab Desktop

General in usability, focused in application
Picking up data from practically any source, manipulating them in any way, and then creating great reports is easy with Test.Lab Desktop! And anyone with basic Windows skills can operate it. Browse over and into data files using a familiar Explorer-like interface. Just click on a function and the data automatically load onto the display. Search for data using context strings - such as the name of the person that performed the test, the configuration of the subject, date of the measurement, or other vital details. You can even bookmark important data so that you can find them easily weeks later. Data can be accessed without anyone needing to know which particular application program was used to acquire them. Or how it operates. The Desktop eliminates the trouble of having to learn another code just to make a report.

Total transparency
The Desktop works transparently with data from any source. In fact, there’s no need to copy, convert or even know where the data resides. Data acquired by legacy systems can easily be compared to something measured today using the latest equipment. You can access competitive benchmarks acquired by another department - or compare the status of the latest prototype with the results of the previous model measured years ago. Being able to access all these data in a transparent way means you can leverage the investments you made in the past.

Reveal the hidden problems
Noise and vibration problems are often caused by subtle events: the troublesome 3rd order that is nearly but not quite masked by background noise; the local mode just at the point where you need to connect a sensitive component; the annoying rattle that develops over time… To spot small details, you need powerful graphical displays with very flexible display limit settings, a choice of viewing angles, and even a choice of colour scales and line formats. The Desktop graphics provide you with everything you need for noise and vibration engineering – and everything has been tuned by years of LMS experience. 

Compare and you will understand
Often insight only comes by comparing data - which may not be an easy job when measurements were made by different people, incompatible equipment or even at different times. With Test.Lab Desktop you can align spectra with different resolutions into PSDs, scale them, change acoustic weightings, smooth curves, and perform a host of other operations – at the click of an icon. The system automatically takes care of unit conversion - so you can never make a mistake overlaying data measured in millimetres, meters, or inches, for example. Don’t worry about your original data: they remain unchanged. Cursors will help you to jump to the peak in the overall level and read-out the difference with the status of a year ago. Reference curves stored with the display layout will immediately tell you whether you meet the target, or not. You can even make comparisons by listening to the data. 

Document your data
Test.Lab helps you to document the huge amount of data that a typical laboratory generates every week. You can add key information to the raw data, such as measurement set-up and operator details, descriptions of the test object and testing conditions for data traceability, as well as digital images showing the actual test set-up. Better documentation means your data will retain their value long after the testing phase has been completed.

Make compelling reports
To make your point to your customer, your supplier or your manager, you need a report that really does justice to your work. Test.Lab will help. You can combine trace, waterfall, and surface-shaded animations along with labels, lines, logos,... to maintain corporate standards. Use arrows, text balloons, … and all the features Microsoft Office provides to highlight the really important elements. Once you have a template, the Desktop automatically fills in the data-specific details - such as channel number, axis limits, cursor readouts,… as the report is produced. At a stroke, the need for tedious copy and paste work is eliminated - and consistency within the company guaranteed. 

Bring reports to life
The reports can be made in the traditional Word and PowerPoint applications, and saved in PDF and HTML e-reporting standards. With OLE/ActiveX technologies your documents are not static dry reports, but dynamic entities so that other readers can manipulate the data formats and animation viewpoints to suit their particular requirements.

The gateway to extended analysis
Sometimes you need more than just data visualization: you need to see the level of a critical order, calculate the average of multiple runs, or to visualize the measurements as an animation. The Desktop is the gateway to advanced post-processing options, such as signature processing, operating deflection shapes (ODS), real-time animation, time data analysis or modal analysis. They appear together in the Desktop ‘workflow bar’, so you can arbitrarily flip from a waterfall display to an ODS animation - and back again - by just a click of the mouse.

Organize your data
As the amount of Test data grows, it becomes essential to keep track of them. You need a system that makes data annotation over multiple users consistent - one that relates measurement results to the structure of your product, one that speeds up data search and retrieval. You can extend the LMS Test.Lab Desktop with LMS Tec.Manager, specifically developed for the organization of engineering data from the test, analysis, and other departments, and fully integrated with Test.Lab. Anyone in the extended enterprise with a web browser will be able to find data stored 'somewhere on the network'. Finally, the Desktop also supports the ASAM/ODS test data standard, currently being adopted by the automotive industry.

Proceed to Noise and Vibration Testing
Test.Lab Desktop is the launch point for the LMS Test.Lab testing modules. All use the same ‘workbook’ approach, including the Desktop functionality for data retrieval, visualization and reporting.
