Abstract：Intermediatecheck isanimportant meansoflaboratoryqualitycontrol，whichcaneffectivelyfillthe monitoring gaps for possible performance changes of instruments and equipment between calibration cycles.Both domestic and foreign laboratoryaccreditation bodies （such as the China National Accreditation ServiceforConformity Assessment， CNAS）and qualificationcertification departments clearly stipulate that laboratories should establish and implement intermediate check procedures.Thisarticle introduces thecharacteristicsofthecomb generator，clarifies the parameter requirements of the comb generator for intermediate check of the EMC emisson system，analyzes the specific process of intermediate check，and elaborates on the key points of implementing intermediate check，which is expected to provide assistance for the intermediate check work of laboratories.

Keywords： intermediate check; comb generator; conducted emission system; radiated emission system
