Section 2.2 Windows Operating System
Although LMS Test.Lab 15A was developed on Windows 7 Enterprise 64 bit, it
Chapter 2 Test.Lab configuration
12 Test.Lab Release notes
is broadly tested and supported on the following operating systems:
� Window 7, Professional, Ultimate & Enterprise , 32-bit version
� Window 7, Professional, Ultimate & Enterprise, 64-bit version
� Window 8, Professional & Enterprise, 64-bit version
� Window 8.1, Professional & Enterprise, 64-bit version
The LMS Test.Lab 15A standard installation is compiled in 32-bit mode. There
is however a benefit of using LMS Test.Lab 15A on Microsoft Windows 7 64-
bit: whereas for the classical 32-bit operating system the maximum memory
space for LMS Test.Lab is limited to 2GB, this increases to 4GB when using the
Microsoft Windows 7 64-bit .
Although Microsoft Windows 7 64-bit claims full support of 32-bit
applications, verification has indicated the following restriction for Sound
Diagnosis & Replay (TL-ACT.58.2/3):
� Replay to Head Acoustics HPS with RME audio card does not transfer
HMS encoding. Workaround: set Field type and range manually on HPS
Siemens PLM Software has developed a genuine 64-bit version for most LMS
Test.Lab applications, which is available on request. The 32-bit version being
the advised one, the 64-bit version brings improvement in those cases of very
high memory demands.
Section 2.3 Interoperability with Office (Word and PowerPoint)
Test.Lab supports interoperability with Microsoft Office 2007, Office 2010 and
Office 2013 (excluding Office 365).

Section 3.1 Licensing
The LMS Test.Lab Rev 15A installation includes version 10.1.2 of the license
server, based on RLM 10.1.
Section 3.2 Desktop
� Analyze related data easily with extended coupled cursors
The coupled cursors functionality, allowing direct interactive comparison of
data in various formats, is further extended to include coupled cursors on axis
with related units. When a cursor is selected on an absolute time X-axis,
coupled cursors will also appear in those pictures showing the corresponding
throughput time or rpm as X-axis. This functionality is also supported in active
pictures.
� General display enhancements
The Y-axis context menu is extended with:
� A "more" selection to switch to alternate unit labels of compatible
quantities. The extended list also indicates the quantity case.
� Hatching in the octave display
� Weighting in octave and spectral displays. The overall level bar adapts.
� New "keep peaks" smoothing.
� 3D displays enhancements
The geometry and 3D animation displays are extended with a copy/paste format
capability. This allows aligning the viewing angle and other display features
between views within the same quad display or across displays easily. Settings
from a left/right display can be copied to a upper/lower display, or settings from
a single display can be copied to a quad display. This functionality is not
Chapter 3 What’s new in LMS Test.Lab 15A?

supported in ODS and time animation yet.
The font size of the nodes in display can be selected as small, medium or large.
� Data Management
� LMS Test.Lab 15A supports ASAM ODS standard 5.3.
Section 3.3 Acquisition applications
� Sorting and filtering in the channel list
To facilitate defining, modifying and reviewing channel parameters for high-
channel count configurations, advanced filter and sort capabilities have been
introduced in the LMS Test.Lab 15A channel list. Rows of channels are hidden
based on filter operations on the properties defined in the channel list columns.
It is possible to combine filters for different properties.
� Extended support of SCADAS XS
The LMS Test.Lab 15A Impact Testing workbook supports the handheld LMS
SCADAS XS in front-end mode over USB-3. The LMS Test.Lab Signature
Acquisition and Testing workbooks and add-ins, and the Sound Intensity
Testing workbook supported the LMS SCADAS XS since Rev 14A.
� Extended CAN & FlexRAY support
With LMS Test.Lab 15A, the user can modify or add CAN settings such as the
selection of the .dbc file, the selected channels and their units in that file, and
apply these changes without the need to close and reopen the .lms project file.
The CAN and/or FlexRAY channels will appear in the channel list after an
"apply" action of the user. The corresponding point ids can be edited, and the
channels can be switched on and off as regular channels.
As data for many of the CAN channels is available on the vehicle bus at (very)
low update rates only, the corresponding fixed-sample-rate traces often appear
to be step-functions. In LMS Test.Lab 15A, the user can opt to apply
interpolation between consecutive CAN-message values, and thus record a
smoothed trace.
� Support of the OBD-II On-board Diagnostics bus
On all LMS SCADAS devices, including LMS SCADAS XS, all CAN modules
(except CN-2) support now the OBD-II on-board diagnostics data-stream. This
provides standardized access to status parameters of various subsystems of
almost any vehicle, through a J1962 connector. Older LMS SCADAS hardware
requires a firmware update to activate OBD-II support.
In the LMS Test.Lab 15A workbooks supporting CAN, the OBD-II channels
are handled in a similar way as CAN channels.
� New Pass-by Noise solutions for track-based and in-vehicle testing
The LMS SCADAS solutions portfolio includes a new generation of hardware
supporting all measurement scenarios for exterior Pass-by Noise testing, using
Chapter 3 What’s new in LMS Test.Lab 15A?
Rev 15A 17
track-based or in-vehicle configurations. LMS Test.Lab 15A further extends the
application software for interior and exterior PBN, covering the latest standards
and including a driver’s aid to maximize the rate at which valid tests can be
performed.
� LMS SCADAS Dual Video Camera Module
The LMS Test.Lab 15A Durability Acquisition, Durability Recording,
Acquisition Setup and Time Data Acquisition workbooks support the new LMS
SCADAS CIM-2 Dual Video Camera input module. With this module, video
images from 1 to 30 fps for 2 SONY SNC-CH110 cameras are recorded and
stored in one mp4 file for each camera. The resolution and aspect ratio is user
selectable. The cameras use Power-over-Ethernet through the same rugged
LEMO cable connection to the SCADAS module that also transfers the video
images. The video recording as such is supported in LMS SCADAS Recorder
mode, and not yet supported in front-end mode.
� LMS SCADAS VCF4 module
The LMS SCADAS VCF4 supports four channel signal conditioning and signal
processing for ICP and piezoelectric/charge sensors in one LMS SCADAS Lab
slot. Each VCF4 channel offers the unique combination of a floating input and
an analog monitoring output. For each channel, a monitoring output is available
through a grounded CAMAC connector.
� Automatic start of LMS SCADAS Recorder data recording
In the template definition for the LMS SCADAS Recorder, the user can opt for
an automatic start of the acquisition when the boot sequence of the recorder is
completed. A new generation power supply makes the LMS SCADAS Recorder
automatically boot when external power is switched on.
� User selectable Bluetooth ON/OFF on LMS SCADAS Recorder
In the template definition for the LMS SCADAS Recorder, the user can opt to
switch the Bluetooth communication off. Doing so, the LMS SCADAS
Recorder can no longer connect over Bluetooth to the LMS Smart Control on a
tablet and thus functions in full autonomous mode.
The newest generation LMS SCADAS Recorder supports WiFi to communicate
between the LMS Smart Control tablet instead of Bluetooth.
� Data acquisition hardware traceability
The front-end description file (.fec) is automatically duplicated with a copy of
which the filename includes the front-end type and serial numbers of master &
salve frames.

Section 3.4 Rotating Machinery Testing
Section 3.4.1 Signature acquisition & processing
� Extended missing pulse correction
In LMS Test.Lab 15A, the capability to correct rpm signals for various
configurations of missing pulses is further extended. In case of magnetic pick-
ups for example, the pulses before and after the missing one(s) are typically also
distorted. The user has various new options to skip such pulses, and missing and
double pulse corrections can now be enabled separately. The settings can thus
be optimized to obtain the best possible instantaneous RPM values even for
very irregular pulse trains and/or poor pick-ups. These correction settings are
available as well for online and offline tacho handling.
� Support of Resolvers to measure absolute angle and rotational speed
Resolvers are more and more used to obtain shaft angle position and/or speeds
of electrical motors. In LMS Test.Lab 15A Virtual Channels and Time Signal
Calculator, the resolver signals can be directly demodulated to measure absolute
angle and shaft speed.
� Cycle based angle vs. time
The LMS Test.Lab 15A Time Signal Calculator support the WRAP_ANGLE
function to convert a continuous angle vs. time trace into a saw-tooth function,
using a cycle definition by the user in the angle units. The user can thus quickly
evaluate the occurrence of specific phenomena in relation to cycles, without the
need to switch from the time domain to the angle domain.
� Peak-to-Peak amplitude format for spectra
To allow for immediate interpretation of spectral harmonic content as peak-to-
peak amplitudes, a peak-to-peak amplitude format has been added as extra
option in the channel processing tabs.
Section 3.4.2 Angle Domain Acquisition & Processing
In LMS Test.Lab 15A, the angle domain processing is extended with new
functions.
The "gated block" function cuts segments between user defined angle values per
cycle, to calculate frame statistics such as MIN or MAX in these specific
segments. In a similar way, the signal value at specific angle positions for each
cycle can be extracted.
To avoid aliasing in the order domain, the user can select appropriate anti-
aliasing filters when doing spectral processing on angle domain data.

Rev 15A 19
Section 3.5 Structural Acquisition
Section 3.5.1 Impact Testing
LMS Test.Lab 15A Impact Testing supports the LMS SCADAS XS handheld
front-end. Using e.g. a Microsoft Surface Pro or Panasonic Toughpad tablet
PC, and combined with the LMS Test.Lab operational data acquisition &
analysis workbooks, this offers the user a powerful and extremely portable
solution for NVH troubleshooting.
Section 3.5.2 MIMO FRF
With LMS Test.Lab 15A, the “shaped pure random” excitation mode is added
to the list of excitation modes supported in the MIMO FRF workbook. The
excitation spectra can be arbitrary shaped, and the energy is distributed over the
full bandwidth, thus not limited to the spectral lines.
New phase randomization approaches are available for the periodic random and
pseudo random modes of excitation.
Section 3.5.3 MIMO Sine Sweep and Stepped Sine Testing
� Maximum excitation frequency for MIMO SINE is increased to 40 KHz
The maximum excitation frequency supported by the LMS Test.Lab 15A
MIMO Stepped Sine and MIMO Swepped Sine Testing workbooks is increased
to 40 KHz, to better support resonance identification on small, light and stiff
components such as turbine blades. Depending on the LMS SCADAS hardware
configuration, this maximum frequency might not be available. In this case a
software warning is given.
� Extension of excitation modes for system identification prior to MIMO Sine tests
All excitation modes as available in the LMS Test.Lab MIMO FRF workbook
are now supported in the system identification stage of the MIMO SINE
workbooks. This includes pseudo- and periodic random, true (shaped) random
and arbitrary source signals.
Chapter 3 What’s new in LMS Test.Lab 15A?
20 Test.Lab Release notes
Section 3.5.4 MIMO Normal Mode Testing
� "Reaching Abort Level" warning
A message warns the user that the levels on a channel are reaching the abort
levels. This allows you to avoid unwanted aborts, e.g. during manual tuning.
The levels at which green/orange/red warnings are generated are user definable.
� Recording time data for a tuned mode
LMS Test.Lab 15A Normal Mode Testing provides the option to record & save
time series once a mode is tuned, along with the mode-set and spectral data.
This offers the possibility to analyze these time data offline using various
processing methods. The sample rate and duration are user definable.
Chapter 3 What’s new in LMS Test.Lab 15A?
Rev 15A 21
Section 3.6 Structural Analysis
Section 3.6.1 Modal Analysis
� LMS Test.Lab 15A Modal Analysis supports Generalized Modal Mass
calculation. This calculation uses a scaling scheme in which the maximum
shape value of each modal vector is scaled to unity prior to calculating the
modal masses.
� The FRF synthesis tools are expanded with "partial band synthesis". This
enables quick validation and residual error quantification between measured
and synthesized FRF, when comparing various modal parameter estimation
results in a limited frequency band. This is useful when analyzing &
selecting closely spaced or highly coupled modes. Multiple band selection
criteria are available, and the resulting partial FRF can be stored for
comparison & reporting purposes.
� An automatic save mode is available. Activating this mode will
automatically save the modal analysis results for each calculation in the
active project/section, without further user interaction.
� New point/DoF filters are supported to facilitate the creation of a subset of
measured DoF before analysis or visualization.
Section 3.6.2 Geometry
� The geometry and 3D animation displays are extended with a copy/paste
format capability. This allows aligning the viewing angle and other display
features between views within the same quad display or across displays
easily. Settings from a left/right display can be copied to a upper/lower
display, or settings from a single display can be copied to a quad display.
This functionality is not supported in ODS and time animation yet.
� The font size of the nodes in display can be selected as small, medium or
large.
Section 3.7 Environmental Testing
Section 3.7.1 All Control workbooks
� Notching & Limiting Prediction
To avoid over-testing, notching and limiting are often applied to set safety
Chapter 3 What’s new in LMS Test.Lab 15A?
22 Test.Lab Release notes
limits on absolute accelerations, reached at resonant conditions. In LMS
Test.Lab 15A, the effect of notching & limiting profiles can be predicted
upfront, based on the structural dynamics characteristics as measured on the test
item itself during a low level excitation validation tests or preceding full level
vibration control tests. Various selection & display options are supported to
analyze the predictions before or during the test preparation. The add-in is also
supported in the LMS Test.Lab 15A Desktop.
In LMS Test.Lab 15A Sine Control, a separate setting is introduced to define
the action to be taken when overload on the notch channels would occur. This
setting is clearly separated from the actions requested for control and
measurement channels.
� Test setup logging
LMS Test.Lab 15A automatically generates a nicely formatted "print-setup"
MS-Word document with the relevant parameters for the actual test run, and
attaches this to the run folder for each vibration control test.
Section 3.7.2 MIMO Random
� Profile Matrix from operational data sets
In LMS Test.Lab 15 the profile matrix can be filled automatically using e.g. a
PSD or CSD data set from an operational test. The application will use the Point
ID’s to map the measured data on the target profile matrix cells. This new
functionality eliminates the need for manual interaction during the profile
matrix generation, but requires full consistency between measurement node
naming in the operational data set(s) and the MIMO vibration control set-up.
Section 3.8 Acoustic Testing
Section 3.8.1 Material Testing
� Sound Absorption Testing in room
LMS Test.Lab 15A adds a new dedicated application for Sound Absorption
testing in reverberant rooms. The LMS Sound Absorption Testing in room
Workbook is an easy and intuitive application that guides the user through full
size reverberation room measurements (according to ISO 354 and ASTM C423)
or scaled rooms (alpha cabin method) measurements.
This workbook measures sound absorption for inhomogeneous and large
dimension samples or full objects (i.e. car seat), for random incidence sound, in
a more realistic environment with respect to the absorption in tube methods with
normal incidence.
Chapter 3 What’s new in LMS Test.Lab 15A?
Rev 15A 23
� Sound Absorption Testing using impedance tube
LMS Test.Lab 15A Sound Absorption Testing using impedance tube has been
executed with new capabilities: (1) measure with different tubes and merge the
results in a single final curve. (2) As recommended by the standard, a sufficient
number of test samples must be tested to obtain statistical reliable data. This
statistical analysis is now integrated in the workflow of this workbook in order
to simplify the procedure for the user.
The new LMS Test.Lab 15A Sound Absorption Testing using impedance tube is
easier and more compact than in the past, and better guides the user through the
full test procedure
Section 3.8.2 Sound Quality Metrics
� Time Varying Sharpness The set of Sharpness metrics is extended with a series of Time Varying
Sharpness metrics for diffuse and free field conditions. The original LMS
Test.Lab as Aures (absolute) as DIN45692 (Von Bismark) methods are
supported as well.
Section 3.8.3 Sound Power
� ISO 3744:2010 Sound Power
LMS Test.Lab 15A supports ISO 3744:2010 Sound Power calculations during
the measurements (online, Signature Acquisition workbooks) and in throughput
processing mode (offline, Signature Throughput Processing workbook) for
engineering analysis and for certification. This requires the add-ins ANSI/IEC
Octave Filtering (RTO) and Sound Power based on Sound Pressure. The user is
guided through the various steps of the measurement process. The appropriate
background noise and environmental correction factors are fully supported, and
the application validates compatibility with the ISO3744 standard. Warning
messages are generated when the actual set-up parameters deviate from the
standard.
The Sound Power procedure is supported for stationary as well as for time
varying (tracked mode) tests.
Section 3.8.4 HD and 3D Acoustic Camera
� Batch processing & comparison of multiple data sets
The Sound Source Localization solutions are expanding with LMS Test.Lab15A
with the introduction of 2 new workbooks designed to cope with the large data
volumes that need to be measured, processed and managed.
The LMS Test.Lab Array Batch Processing Workbook automates the processing
Chapter 3 What’s new in LMS Test.Lab 15A?
24 Test.Lab Release notes
of large data volumes. A 64-bit processing kernel boosts productivity by
significantly reducing processing time.
In the LMS Test.Lab Array Data Comparison & Reporting Workbook different
processing results from multiple test runs are compared directly, side by side.
This considerably speeds up the interpretation of test results, come to the right
conclusions, and translate these into actionable reports. Localization results
obtained from different methods and frequency bands, distributed over different
databases, can be selected and lined up for display. Convenient side-by-side
comparison of sound source localization results for different design
modifications and frequencies speeds up analysis & reporting.
� Background picture handling
Other new LMS Test.Lab 15A features include the import, appropriate resizing
and array centering of pictures taken upfront. To easily switch from far-field to
near-field measurement, also a new picture zooming capability is introduced.
Section 3.8.5 Pass-by Noise
� Covering the next PBN standards for EV and In-Room PBN
PBN standards are evolving rapidly. Certification methods get ever more
stringent and noise emission limits ever lower. In parallel with the introduction
of the new LMS SCADAS hardware solutions for track-based and in-vehicle
PBN testing, LMS Test.Lab 15A further extends the support of the latest
standards and procedures, while keeping a clear focus on productivity,
efficiency and engineering insight.
To align with the latest developments in the ISO and UN/ECE GRB
workgroups, LMS Test.Lab 15A introduces 2 new standards:
� ISO16254 (equivalent to SAE J2889-1): a standard for hybrid and electrical
vehicles imposing minimum noise limits on cars driving at slow speeds
and/or at stand still positions
� ISO 362-3 describing certification using an in-room PBN set-up, requiring
the derivation and inclusion of a tire noise model based on exterior PBN
measurements
Both standards will be part of the legislation around the world in due time, and
are supported in the LMS Test.Lab 15A software.
� Guiding the test driver with the PBN Driver’s Aid app
The LMS Smart PBN Driver’s Aid app runs on a tablet and interacts with the
new SCADAS-based PBN hardware to provide real-time information to the
driver on actual & target speed, and on vehicle position. This helps drivers
maximize the success rate of executing valid PBN runs, something which is not
obvious anymore with the new where the vehicle needs to drive 50km/h at the
center line during acceleration. After validating the kick-down point, the target
approach speed is automatically updated to be aligned with the ISO362:2007
standard, and shown on the Smart DA app in the vehicle. This helps drivers
meeting the target center speed, and improves the overall testing productivity.
Chapter 3 What’s new in LMS Test.Lab 15A?
Rev 15A 25
� Engineering insights from TPA/ASQ analysis
The LMS Test.Lab 15A Interior and Exterior Pass-by Noise solutions
seamlessly link into the LMS Test.Lab TPA/ASQ application workbooks for
root cause contribution analysis. The various contributions can be analyzed in
detail in a PBN-specific tab-sheet of the TPA workbook.
Section 3.8.6 Transfer Path Analysis
� TPA-based sound quality engineering
The LMS Test.Lab TPA Synthesis Workbook extends the use of conventional
and full binaural TPA models for sound design and sound quality engineering.
Replay and filtering capabilities allow you to make decisions faster and better,
based on a combination of objective and subjective criteria.
During replay, paths can be activated, deactivated or filtered in real-time,
enabling you to assess individual paths or group contributions for various
operating conditions. Output signals are processed in real time for objective
evaluation. These new source-ranking functions can be used for
troubleshooting, refinement, or as part of a target cascading process to vehicle
subsystem levels.
LMS Test.Lab 15A extends the capabilities of the TPA Synthesis workbook by
facilitating the comparison between different "what-if model modifications".
The user can save these different "views" created by switching paths on or off,
applying specific filters or scale factors etc. He also can save the synthesized
target data sets for these views. The application provides guidance by proposing
filenames based on e.g. the path grouping or view definitions. For immediate
subjective comparison between different modifications, the user can switch
during the audio replay directly between various saved models, uploaded in the
playlist. These synthesized targets can be further processed to obtain Sound
Quality metrics, for quantification of the changes against the original measured
situation.
Section 3.9 Time Data Acquisition
The Time Data Acquisition section groups the products related to the LMS
Test.Lab Durability portfolio: Durability Recording, Durability Acquisition and
Durability Processing. With the release of LMS Test.Lab 15A, a separate
Desktop workbook has become part of this portfolio, and a new Time Data
Acquisition workbook is added, to support more generic throughput acquisition
tasks. Application specific defaults differentiating between Durability, NVH or
generic use cases can be selected at installation.

Section 3.9.2 Acquisition Setup
The LMS Test.Lab Acquisition Setup workbook covers the functionality to
define the measurement setup and manage the channel lists, functionalities
which are shared across the Durability Recording, Durability Acquisition and
Time Data Acquisition workbooks. Following new capabilities are introduced
with LMS Test.Lab 15A:
� LMS SCADAS Dual Video Camera Module
The LMS Test.Lab 15A Durability Acquisition, Durability Recording,
Acquisition Setup and Time Data Acquisition workbooks support the new LMS
SCADAS CIM-2 Dual Video Camera input module. With this module, video
images from 1 to 30 fps for 2 SONY SNC-CH110 cameras are recorded and
stored in one mp4 file for each camera. The resolution and aspect ratio is user
selectable. The cameras use Power-over-Ethernet through the same rugged
LEMO cable connection to the SCADAS module that also transfers the video
images. The video recording as such is supported in LMS SCADAS Recorder
mode, and not yet supported in front-end mode.
� Extended support of LMS SCADAS XS
The LMS Test.Lab 15A Acquisition Setup workbook now also supports the
definition of autonomous recording setups for the LMS SCADAS XS (recorder
mode).
The LMS Test.Lab 15A Time Data Acquisition workbook supports the LMS
SCADAS XS in front-end mode.
� Extended CAN support
With LMS Test.Lab 15A, the user can modify or add CAN settings such as the
selection of the .dbc file, the selected channels and their units in that file, and
apply these changes without the need to close and reopen the .lms project file.
The CAN channels will appear in the channel list after an "apply" action of the
user. The corresponding point ids can be edited, and the channels can be
switched on and off as regular channels.
As data for many of the CAN channels are available on the vehicle bus at (very)
low update rates only, the corresponding fixed-sample-rate traces often appear
to be step-functions. In LMS Test.Lab 15A, the user can opt to apply
interpolation between consecutive CAN-message values, and thus record a
smoothed trace.
� Support of the OBD-II On-board Diagnostics bus
On all LMS SCADAS devices, including LMS SCADAS XS, all CAN modules
(except CN-2) now support the OBD-II on-board diagnostics data-stream. This
provides standardized access to status parameters of various subsystems of
almost any vehicle, through a J1962 connector. Older LMS SCADAS hardware
requires a firmware update to activate OBD-II support.
In the LMS Test.Lab 15A workbooks supporting CAN, the OBD-II channels
are handled in a similar way as CAN channels.

� Channel Setup extensions
The active channel list with user-definable view configurations (including
selection, sorting, filtering and grouping of channel list properties) is further
enriched with:
� Extended support of class I and II TEDS formats (IEEE 1451.4). This
includes a.o. support of offsets & limits, interactive/selective acceptance of
TEDS properties for individual or subsets of channels.
� Support of multiple sensor databases via ODBC, with a user defined
hierarchy. Similar to TEDS, an interactive/selective acceptance of read-out
properties is supported.
In support of NVH specific recording and throughput acquisition scenario’s,
three types of binaural channels are supported:
� The LMS Analog Binaural Headset
� Conventional Analog binaural transducers
� Digital binaural transducers (SPDIF, e.g. from Head Acoustics, including
support of relevant HMS parameters)
The corresponding channel properties include channel coupling, equalization
state, sound field definition, and range definition in dB.
In LMS Test.Lab 15A, the supported calibration procedures are extended and
now include AC calibration in linear or dB units. Calibrators can be selected
from a list of commercially available calibrators (e.g. from G.R.A.S or B&K).
The calibration setup is automatically adapted using the calibrator parameter
such as level, unit format and calibration frequency.
Section 3.9.3 Durability Recording and Acquisition
The LMS Test.Lab Durability Recording Workbook allows to set up a channel
configuration, scope data, write SCADAS Recorder templates and import
SCADAS Recorder files (*.trp). The functionality is tuned to the SCADAS
Durability Recorder autonomous recording use cases.
The LMS Test.Lab Durability Acquisition workbook adds the direct
measurement of throughput files to a PC harddisc (LMS SCADAS front-end
mode) and support the calculation of virtual channels during such front-end
measurement or at import of Recorder file (*.trp). The calculation of advanced
statistics is also supported.
With LMS Test.Lab 15A, several extensions are introduced to further complete
the coverage of multi-sensor-type test setups by the Durability Acquisition and
Durability Recording workbooks. This functionality is shared with the
Acquisition Setup Workbook, and the details can be found in the corresponding
section above.

Section 3.9.4 Durability Online Processing
This add-in on top of the LMS Test.Lab Durability Acquisition Workbook
performs on-line calculations of counting operations, such as rain-flow and
histograms, during scoping or front-end data acquisition. The appropriate
parameters for pre-processing (e.g. hysteresis filtering) can be set by the user.
The supported histogram functions are Range Pair, Level Crossing and Time at
Level.
With LMS Test.Lab 15A, the processing is extended with averaged autopowers.
Section 3.9.5 Time Data Acquisition
The LMS Test.Lab Time Data Acquisition workbook is a new workbook that
targets the coverage of more generic NVH data recording and throughput
acquisition scenarios. With LMS Test.Lab 15A, functional extensions to better
support such test set-ups for generic and NVH specific use cases are released.
As the test set-up definition is shared with the Acquisition Setup workbook, the
details can be found in the corresponding section above.
