FFT analyzer
The FFT analysis in LMS Test.Xpress uses narrow-band frequency
analysis and offers multiple real-time analysis of basic FFT’s, zoomed
FFT’s, PSD’s, crosspowers, FRF’s, coherences, etc. It allows you to
quickly determine resonances, damping values or harmonic content
from the frequency spectrum, averaged or tracked to a specific channel.
Functions such as envelope, Hilbert transform and Cepstrum allow to
do advanced machine diagnostics. The FFT analysis can be combined
with any of the other analyzer functions in Test.Xpress without losing
performance, which supports a simultaneous multi-analysis of the data.
Octave analyzer
The LMS Test.Xpress octave analysis is the ideal solution to
troubleshoot acoustic problems. The software supports 1/1, 1/3rd,
1/6th, 1/12th and 1/24th octave filter functions according to IEC and
ANSII standards, allaveraged or tracked against a specific channel.
Other functions such as Leq, reverberation time (T60) calculation
and online Articulation Index and Loudness turn it into an advanced
acoustics analyzer. To perform a simultaneous multi-analysis of your
data, you combine the octave analysis with any of the other analyzer
types in Test.Xpress. The LMS SCADAS front-end has no cooling fan
and provides the silent operation required for acoustic testing.
Order analyzer 
The LMS Test.Xpress order analysis function calculates order maps,
single order cuts, overall levels, etc. The system resamples data
relative to a specific rpm or speed channel and clearly shows you
all the speed related phenomena that are hidden in the data. For
industrial applications, LMS Test.Xpress offers tacho conditioning
and digital processing tools via 2 dedicated tacho inputs or
simply using any dynamic channel. This guarantees accurate
measurement results, even in case of rapidly accelerating shafts.
Throughput recorder
Parallel to the analyzer applications, you can use LMS Test.Xpress
as a sound and vibration throughput recorder. The system directly
streams data to disk, offering gap-free recording of 40 channels at
full bandwidth, without affecting the real-time analyzer performance.
While the system records to disk, you can open previous measurements
on the same PC, run post-processing calculations, replay audio
channels and view results. Advanced triggering capabilities with
pre- and post-trigger allow the system to operate independently,
and start data recording when a specific event occurs.
Data viewing and reporting
All LMS Test.Xpress analyzer functions include the ability to open
different data – even coming from external sources – display, compare
and analyze them in different layouts. You can even run Test.Xpress on
a separate PC and use it as a standalone data viewer. LMS Test.Xpress
includes a variety of tools to help you finish your report with a minimum
of fuss. You can easily drag and drop data into displays, copy and paste
displays or use the default reports in html, word or excel format, all this
using Windows standard XML based reporting. You can easily create and
modify your own reporting formats without any need for programming:
insert your company logo, change the layout, perform further analysis
in excel and create the final graphs you need in your new template.
