11 Chapter 2 Test.Lab configuration Chapter 2 Test.Lab configuration In This Chapter Recommended PC Hardware Windows Operating System Interoperability with Office (Word and PowerPoint) Screen Resolution Interoperability with other LMS products Section 2.1 Recommended PC Hardware This is the configuration used by Siemens for benchmarking and quality testing, and that is recommended to be used with the Test.Lab 15A product suite. Section Laptop PCs Section Dell precision M4800 Intel i7 cpu 16GB RAM 600GB sata (7200 rpm) NVIDIA Quadro K1100M Section Desktop PCs Section Dell Precision T3610 Intel Xeon E GB RAM 1T SATA disk (15000 rpm) NVIDIA Quadro NVS 310 (Graphics card) Section 2.2 Windows Operating System Although LMS Test.Lab 15A was developed on Windows 7 Enterprise 64 bit, it Rev 15A 11

12 Chapter 2 Test.Lab configuration 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 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).

15 Chapter 3 What s new in LMS Test.Lab 15A? Chapter 3 What s new in LMS Test.Lab 15A? In This Chapter Licensing Desktop Acquisition applications Rotating Machinery Testing Structural Acquisition Structural Analysis Environmental Testing Acoustic Testing Time Data Acquisition Section 3.1 Licensing The LMS Test.Lab Rev 15A installation includes version of the license server, based on RLM 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 Rev 15A 15

16 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 highchannel 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 16 Test.Lab Release notes

17 Chapter 3 What s new in LMS Test.Lab 15A? 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. Rev 15A 17

18 Chapter 3 What s new in LMS Test.Lab 15A? Section 3.4 Rotating Machinery Testing Section 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 pickups 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-topeak amplitudes, a peak-to-peak amplitude format has been added as extra option in the channel processing tabs. Section 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 antialiasing filters when doing spectral processing on angle domain data. 18 Test.Lab Release notes

19 Chapter 3 What s new in LMS Test.Lab 15A? Section 3.5 Structural Acquisition Section 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 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 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. Rev 15A 19

20 Chapter 3 What s new in LMS Test.Lab 15A? Section 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. 20 Test.Lab Release notes

21 Chapter 3 What s new in LMS Test.Lab 15A? Section 3.6 Structural Analysis Section 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 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 All Control workbooks Notching & Limiting Prediction To avoid over-testing, notching and limiting are often applied to set safety Rev 15A 21

22 Chapter 3 What s new in LMS Test.Lab 15A? 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 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 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. 22 Test.Lab Release notes

23 Chapter 3 What s new in LMS Test.Lab 15A? 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 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 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 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 Rev 15A 23

24 Chapter 3 What s new in LMS Test.Lab 15A? 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 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 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. 24 Test.Lab Release notes

25 Chapter 3 What s new in LMS Test.Lab 15A? 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 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. Rev 15A 25

26 Chapter 3 What s new in LMS Test.Lab 15A? Section Desktop for time data acquisition All Time Data Acquisition workbooks (Acquisition Setup, Durability Recording, Durability Acquisition, Time Data Acquisition) share the same navigator sheet, offering following functionality, which is now also available as separate Desktop workbook: Data viewing & validation of measured and processed time series, blocks, rain-flow data etc, with multi-trace and overlay display options Quick data organization with multiple data presentation approaches, including folders, list views and a pivot views. Sorting & filtering can be applied, and the resulting data visualization format can be saved for later use. A subset of the saved views can be tagged as "favorites" Automatic previews of selected data, using defaults display formats for the data type for easy data validation and comparison One-click visualization of data properties, with customizable views of subsets of key properties User defined data annotation model to document measurements at run level to ensure traceability and enhance the comparison of data. The attributes entry menu can be set to appear before or after the measurement run User-defined layout definition Import of LMS SCADAS Recorder.trp and LMS SCADAS XS.xtrp files with conversion to LDSF, with support of batch import Export of trp, xtrp and LDSF time series to multiple formats: IST RigSys, MTS RPC-III, ncode DAC, NI Diadem DAT & TDM, Lexade, MOOG, Head Acoustics HDF, ASCII, Google kml, NMEA, MATLAB, ASAM ATFX. Video & Audio Replay In LMS Test.Lab 15A, 2 new add-ins for the replay of video and audio recordings can be loaded in the Durability Acquisition, Durability Recording, Acquisition Setup, Time Data Acquisition and Desktop workbooks. Playlists for replay can be built from a preview of recorded traces or from a multi-display picture Various options to automatically control the replay sequences of the playlist with or without loops exist Time segments can be defined independently for the various traces in the playlist, to maximally match the segments of interest for comparison. For overlapping time segments, coupled cursors are shown When combining video and audio replay, both are synchronized For video replay only, multiple fast or slow replay speeds can be selected before or during the replay 26 Test.Lab Release notes

27 Chapter 3 What s new in LMS Test.Lab 15A? Section 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. Rev 15A 27

28 Chapter 3 What s new in LMS Test.Lab 15A? 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 ). 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 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. 28 Test.Lab Release notes

29 Chapter 3 What s new in LMS Test.Lab 15A? Section 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 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. Rev 15A 29
