“…In fact, the main objective is to create novel just-before-test methods capable of identifying common failures that recurrently occurs during EMC tests, focusing on conducted emissions and immunity testing. Therefore, we propose fast methods that delay shortly the day-work at EMC test laboratories but at the same time are feasible to identify setup errors or defects on the used instrumentation [5] and [6]. Currently, many times the testing workbench is verified in different stages including several measurement and instrumentation.…”

It is mandatory for EMC test laboratories to apply verification methodologies to ensure that they are performing the tests properly. However, the time-consumption of most of the procedures or its low accuracy causes low-impact and consequently a poor benefit for laboratories. With the aim to improve the performance of the current verification methods, a just-before-test methodology based on time-domain measurements is proposed in this publication. In order to improve the accuracy and detect failures for conducted emissions and immunity tests, arbitrary waveforms and full time-domain EMI measurement methods are combined. Hence, it is proposed to use multi-tone and pulsed waveforms to evaluate the performance of the conducted emissions test, including the receiver with normative detectors, paths and devices like LISN. On the other hand, for the immunity test, a time-domain EMI system based on the use of an oscilloscope is employed to identify defects on the amplifier, RF generator, devices like CDNs or paths. The methodologies are explained and validated through different simulated failure scenarios. Where we can identify a proper performance of the test bench or defects like poor grounding or coupling devices malfunctions.

“…The network filters are designed and realized mainly to reduce the conducted emissions of common and respectively differential mode [9], [10], [11]. Along with supplementary actions meant to provide proper shielding and assembling with the protected electronic equipment, they can also provide a significant reduction of the radiated emissions produced by the switching electronic equipment.…”

The paper deals with the designing, realization and testing of a network filter used to reduce the electromagnetic disturbances produced by static switching equipment. The tests were done according to the CISPR 17 standard for the determination of the insertion loss for each cell, and the verifications concerning the filter's efficiency with respect to the conducted and radiated disturbances produced by a static switching equipment revealed the obeying of the CISPR 11 standard. One presents the experimental determinations made previous to network filter use. After the filter's designing and realization, experimental data relative to the conducted emissions were gathered. The assembling and case shielding were improved in order to obey the limits imposed to the radiated emissions according to the CISPR 11 standards, and consequent experimental determinations revealed significant improvements from the EMI point of view.
