9.2.5 Characteristicvalues
VibrationsignalrecordingsareinitiallysavedtoabufferwithintheI/Omodule.
OptionsareavailabletothenperformanFFTanalysisortocomputeafrequency
spectrum.Itisthenpossibletocalculatevariouscharacteristicvibrationvalues
fromthevibrationsignaland/orthefrequencyspectrum.
Oneormoreadditionalcharacteristicvaluechannelsareavailableforeachana-
logueinputchannel.Thesethendelivercharacteristicvaluesforvibrationdata
(e.g.rootmeansquare,aspectrum'speakamplitudeetc.).
Properties
l 1to30characteristicvaluechannelscanbesetup/createdseparately(for
eachanalogueinput)
l Simpleconfigurationusingselectionlists
l Automaticassigningtosourcechannel
