CompliancewithFCC/CanadaRadioFrequency
InterferenceRegulations
DeterminingFCCClass
TheFederalCommunicationsCommission(FCC)hasrulestoprotect
wirelesscommunicationsfrominterference.TheFCCplacesdigital
electronicsintotwoclasses.TheseclassesareknownasClassA(for
useinindustrial-commerciallocationsonly)orClassB(forusein
residentialorcommerciallocations).AllNationalInstruments(NI)
productsareFCCClassAproducts.
Dependingonwhereitisoperated,thisClassAproductcouldbesubject
torestrictionsintheFCCrules.(InCanada,theDepartmentof
Communications(DOC),ofIndustryCanada,regulateswireless
interferenceinmuchthesameway.)Digitalelectronicsemitweaksignals
duringnormaloperationthatcanaffectradio,television,orotherwireless
products.
AllClassAproductsdisplayasimplewarningstatementofone
paragraphinlengthregardinginterferenceandundesiredoperation.The
FCCruleshaverestrictionsregardingthelocationswhereFCCClassA
productscanbeoperated.
