LMS Test.Lab Signal Calculator[TL-GPR.51.2]

The LMS Test.Lab Time Signal Calculator Workbook is a

member of the LMS Test.Lab General Purpose Processing

product family. The calculator processes time data in a user-

friendly and efficient way, and not only allows a user-

interactive mode of operation, but it is also possible to fit the

calculator in the measurement flow, such that immediately

after the acquisition, additional calculated time traces will be

available. In case the Data Set contains multiple runs, then all

defined operations will be executed in batch mode for each of

the runs.

The Time Signal Calculator includes the Time Data Selection

worksheet and benefits from all functionality offered by this

worksheet (manual or automatic visualization of time data via

powerful stripchart displays, overview or detailed

visualization, segment selection, quick spectral map for

inspection of frequency content, support of different data

types such as LMS TDF, SDF, …).

Calculations can be defined using PointId’s or Trace Id’s.

PointId’s provide maximum flexibility for cabling while

guaranteeing that the correct results are obtained. TraceId’s

allow to speed up the definition of formula’s. Formula’s are

verified for their syntax, and can be saved for later reuse.

Possible calculations include arithmetic operations, fixedresampling, filtering, Tacho-to-rpm conversion, weighting,

integration/differentiation etc. Calculations can be done on

user-definable segments or on the complete trace. Results

can be added to the original run, or can be saved separately.

The processing workbook addresses the needs for time

domain processing in the signature testing process : easy

operation, application focus, user-interactive and open to in-

process automation.

Key benefits

Efficient and user-intuitive timedata processing

Support of multiple data types(LMS TDF, SDF, Pimento, …)

User-Interactive, automated (in-process) or batch mode ofoperation

Formula Sets can be saved forlater reuse. The complete set offormula’s can be applied in asingle calculation step.

Calculations can be applied onuser-definable segments, orover the complete trace

Support of TraceId’s orPointId’s in Formula’s formaximum flexibility

Easy visual validation ofcalculated results, beforesaving

Calculated results can beadded to the original run (forLMS TDF only), or can besaved separately

in Data Set & use button ordrag & drop

Automated viewing : select inData Set + first/last &next/previous buttons

Visibility control of overview,detail and parameter regions

Quick spectral map

Data selection in Data Set list Push calculate button to update No parameters to be defined,

software selects goodparameters automatically

View result in Colormap orWaterfall display

Show/Hide Quick Spectral Mapregion

Formula Setup

Virtually unlimited number offormulae can be defined

Convenient tabular listing offormulae enhancing a quickoverview of all definedcalculations

Support of editing operations:create, delete of individualuser-selectable formulae orclear of complete formulae set,Copy/Past, Hide/Unhide

Complete Formula Set can besaved/loaded

Formula editor provides syntax

checking and verifies thecompatibility with the formulaarguments (units, samplerates. …) to avoid unnecessaryerrors during calculation

Convenient trace renumberingassures unique traceidentification

PointId, Direction and ChannelGroups can be defined duringcreation of the formula,allowing immediate furtherprocessing of the results

Easy selection of processingfunctions via a pop-up dialog:multiple categories are

presented (All, Math,Conditioning, Signal, Tacho)supporting a quick retrieval ofthe required processing.

Convenient help areaexplaining the requiredparameters for the selectedfunction

Parameters of selectedfunctions can be manuallyedited while selection ofTraceId’s or PointId’s can alsobe done via simple mouseclicks

Processing

Complete Formula Set can beprocessed in one step orindividual formulae can beselected for (re)processing

Support of mathematicaloperators (+ , - , * , / ) andsupport of the followingcategories of processing

functions: MathematicalProcessing (Product, Divide, ABS, SQR, SQRT,SIN,COS,TAN,ASIN,ACOS,AT AN), Conditioning Processing(Integrate, Double Integrate,

Differentiate, DoubleDifferentiate, DopplerCorrection, Low-pass filtering,High-pass filtering, Band-Passor Band-Stop filtering, Notch orOrder filtering, A- B- and C-weighting, unweighting ofweighted data), SignalProcessing (Detrend resultingin the AC or DC-component,Fixed Resampling), TachoProcessing (Tacho-Train-to-rpm)

Calculated results canimmediately be reused forfurther processing with the

Signature ThroughputProcessing Add-In

Calculations can be performedon user-definable tracesegments

Calculated traces can be addedto the original run, or can besaved in a separate run.

Process Automation

The formula editor supportsnested formulas, allowing tospeed up the calculation of

results (e.g.Integrate(Detrend_AC(S1)) )

Calculations can be performed immediately after each run,without any user-interactionsupporting repetitive operations

Formula Set and mode ofoperation can be saved to atemplate for quick start-up, andto avoid possible operatorerrors
