The major pitfall is the necessity for the measurement of injected CS101 ripples across the EUT and also across the power source side under the presence of the power frequency of the EUT, whose solutions have been thoroughly studied and introduced in our earlier papers. The other critical pitfall is that the influence of the injection point and the decoupling capacitor position may reach significant levels especially beyond 30 kHz. Therefore, in this research, we extensively study and demonstrate the influence of the positions of the injection point and the $10 mumathrm{F}$ decoupling capacitor on test results especially as from 30 kHz and ultimately propose solutions to this issue.","PeriodicalId":436679,"journal":{"name":"2019 ESA Workshop on Aerospace EMC (Aerospace EMC)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133243770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Susceptibilities may be difficult to detect because in most cases the monitored parameters are not measurable: subjective assessment of immunity is made by human sensory terms. Objective assessment made by monitoring measurable signals is the correct approach to establish unambiguous immunity criteria. However the objective assessment is not sufficient because an objective judgement is also required to avoid personal interpretations. On the basis of these principles this paper illustrates a simple processing algorithm, which can be successfully applied to both simulation and/or experimental results.","PeriodicalId":436679,"journal":{"name":"2019 ESA Workshop on Aerospace EMC (Aerospace EMC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133209379","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
