1 Overview

The Multi-Cal-SystemEvaluationModule isa setofEVMs thatisused tocalibratemultiplePGA308 and PGA309 sensormodules.The PGA308 and PGA309 aretwo programmableanalogsensorsignal conditioners.Allcomponents intheMulti-Cal-Systemcan be expanded tocalibrateup to64 sensors simultaneously.Fora more detaileddescriptionofthePGA308, pleaserefertotheproductdatasheet (SBOS440 )availablefromtheTexas Instrumentsweb siteathttp://www.ti.com.Additionalsupport documents arelistedinthesectionofthisguideentitledRelatedDocumentationfromTexas Instruments. The Multi-Cal-SystemEvaluationModule consistsoftwo printedcircuitboards(PCBs).One board(the USB DAQ Platform)generatesthesignalsrequiredtocommunicatewiththeMulti-Cal-System,whichis thesecond board(Multi-Cal-MasterPCA), as wellas supportand configurationcircuitry.The complete Multi-Cal-Systemcontainsa seriesofPCBs, and can be expanded tomeet yourspecificsystem requirements. Throughoutthisdocument,theabbreviationEVM and thetermevaluationmodule aresynonymous with theMulti-Cal-SystemEvaluationModule.
