EMI Analyst is a 4-in-1 EMI Analysis ToolEMI Analyst calculates electromagnetic interference for cable-connected circuits
Conducted Emissions CE AnalystAF and RF current and voltage emitted on cablesConducted Susceptibility CS AnalystCurrent and voltage induced by interference injected on or coupled to cablingRadiated Emissions RE AnalystElectric and magnetic fields emitted by cablesRadiated Susceptibility RS AnalystCurrent and voltage induced by electromagnetic fields on cable
EMI Analyst
EMI AnalystWhat is EMI Analyst?2
What does RS Analyst do?Calculates current and voltage induced on cabling andend circuits by external electromagnetic fields
