“…The reported results support that, provided the correct signal processing and adequate hardware specifications, oscilloscope-based measurements comply with the relevant CISPR 16-1-1 baseline requirements. Other studies have benchmarked FFT and stepped scan test receivers as part of actual testing scenarios, including CISPR 32 testing of real equipment [14], in-situ emissions assessments of atypical equipment [15], [16], and common-and differential mode conducted emissions measurements [17].…”

This paper compares the measurement results obtained from three different implementations of measuring receivers regarding spectral level accuracy. The objective is to validate the suitability of direct sampling electromagnetic emissions measurements with respect to those delivered by a highend EMI receiver in frequency swept and FFT modes. The experimental setups follow the verification methods described in the ECSS-E-ST-20-07C Rev.2 standard to set realistic and reproducible conditions. Between 50 kHz and 100 MHz, common mode and differential mode currents are measured when multisine excitation signals with controlled amplitude profiles are used as references. Subsequently, conducted and radiated emissions tests are run to investigate the correlation between measurements with the different receivers. The instruments used are a low-cost USB digitiser Picoscope PS5444D, a high-performance benchtop oscilloscope R&S RTO6 and the R&S ESW44 full-compliant EMI test receiver. The analysis concludes that the emissions measurements performed with the direct sampling approach are excellent for the intended application, exhibiting an accuracy comparable to the dedicated EMI test receiver and a welladequate dynamic range and noise level.

“…It is conventional to separate the conducted emission (CE) into a differential mode (DM) and common mode (CM), since those types of noise have different propagation paths, hence are being suppressed by different components in the EMI filter. Additionally, the superposition of DM and CM noise, normal mode (NM), is being assessed and regulated during conducted emission tests, as in CISPR 32 [4].…”

Electromagnetic interference filters are being characterized in terms of their insertion loss. CISPR 17 provides measurement procedures for assessing normal, common, and differential mode insertion loss. Respectively, this requires three different setups to fully characterize the filter. This paper shows an alternative to the CISPR 17 setup resulting in a time-efficient measurement approach that allows the evaluation of all modes of insertion loss of the filter in a single measurement setup. Furthermore, it is extended to an approximate worst-case measurement, as in CISPR 17. Complimentary, the suggested setup is used to perform insertion loss measurements of a filter including line impedance stabilization networks, to assess the more realistic performance of the filter in the conducted emission test.
