Recently, concern has been raised with regard to the adequacy of current verification practices carried out in electromagnetic compatibility (EMC) testing laboratories. Bridging the gap in the scope and reliability of the verifications performed in EMC laboratories requires faster and simpler verification methods to be performed prior testing. This paper presents a verification method for Full Time Domain Electromagnetic Interference measurement systems (Full TDEMI) that is intended to be quick and automated in order to become practical under the “just-before-test” approach. The method comprises a four stage process for assessing: sine-wave voltage accuracy, response to pulses, selectivity and input impedance. The verification method has been implemented and executed on an oscilloscope-based Full TDEMI achieving a reduction of time and effort involved while ensuring the compliance with CISPR 16-1-1 applicable requirements. Finally, this verification method improves the statistical significance because of the large number of points and conditions checked by the measurement automation software.
