ProfiMessage
9.2.3 Timesignal
EveryvibrationsignalrecordedisinitiallysavedtothebufferoftheI/Omodule.
The“analogueinput”channeldeliversablockofmeasurementdata(e.g.2048
amplitudevaluesovertime).Thisblockisreferredtoasatimesignal.
Properties
l 128to8192samples,sampledsynchronously/inparallelat256Hzto20480
kHz
l Variablepre/posthistoryand/ortriggerpoint
l Digitalfilters,integratorsetc.canbeused
l Datacompressioncanbeusedfortransmissionandstorage.
Topics
9.2.3.1 Digitalfilter
Properties
l Choiceoffiltertype:low-pass,band-pass,high-passordemodulationfilter
l Filterordersof2…8,presetButterworthcharacteristic
l Adjustablecut-offfrequencyintherange1Hz…10kHz
l Adjustablefiltersforeachchannel
Application
High-frequencyinterferencesarefilteredoutoftheacquiredsignal.Oronlythe
desiredfrequencyrangeisfilteredoutforanalysis.
Restrictions
Thedigitalfiltersarealsosubjecttotheserestrictionsifapplicable:
l BoardV2.00toV2.12
For1...4analogueinputs:allfiltersavailable,max.orderis8.
For5...8analogueinputs:onlylow-passisavailable,max.orderis4.
l BoardV2.13andhigher
For1...8analogueinputs:allfiltersavailable,max.orderis6.
9.2.3.2 Digitalintegrator
Properties
l Numericalintegrationoftherecordedvibrationsignal
l Fixedscalingfactorpresetat1000.
