MULTI-SLOT VXI MODULES WITH VARIABLE INSTRUMENT CARDSSeries 4000 TMMulti-slot VXI ModulesThe new ASCOR Series4000 VXI modules have beendesigned and developed aftera number of years of buildingMulti-slot VXI modulesfor a variety of differenttest applications. Themajor advantage forthe customer to buyingsuch a product isthat when multiplematrices have to be tiedtogether to create a largematrix, the multiple smallermatrices can all be tied togetherinternally. The customerdoes not have to splice wirestogether.Before the Multi-slot moduleconcept, the solution tocreating a large matrix meantthat the engineer would haveto externally splice the differentmatrices together. In additionto opening and closing relayswithin the newly created largematrix, the engineer wouldhave to address and sendcommands tomultiple VXImodules.Needless to say,not only was theprogrammingcumbersome, butthe ability to controlbandwidth andstub lines wasvirtually non-existent.The advent of the Multi-slotmodule solved thoseissues with dramaticresults. In one documentedexample, theMulti-slot moduleprovides the customerwith 15 MHz bandwidththrough the worst pathof a full 4 x 384 dual-wire matrix.This performance representsa substantialimprovementover the estimated
