resultsfromtimetotime,andmeasurementresultavailabilitymaydependonconfiguration,channelcontent,andoptions
installed.Thismaymeanthataspecificresultisnotalwaysinexactlythesamepositioninthefile.Thefilecontains
columnheadings(androwheadingsforsomeformats),itisrecommendedtousethesetodeterminethemeaningofresults

23.5.3.1 MEASUREMENTS FILE
Thefilecontainseverymeasurement,includingharmonics,inallVPAsandallchannels.
Thesefilesarevariableinlengthandcanbeupto350Kbyteslong.
Thefirstcolumnofeveryrecordcontainsthedescriptionofthatmeasurement,followingthataretheresultsforthatmeasurement
foreachchanneloreachVPAasappropriateineachcolumn.
ThereareseparatesectionsofthefileforchannelbasedandVPAbaseddataandthefirstrecordofeachsectionareheaders
describingeachcolumn.
ThefirstsectionisthedataforeachVPA,belowisanexampleofthefirstfewrecordsoftheVPAdatasection(onlyVPA1has
