In this paper it is shown that the current frequency domain tests are not sufficient to determine the equipment's immunity, because of for instance non-linear effects, including saturation, digital sampling error effects and other non linear time invariant (LTI) effects. Fast changing time domain signals are not covered by the standards. For example cases are described where static energy meters can give misreadings when loaded with pulsed currents. Previous research describes several electromagnetic interference (EMI) cases in this frequency range, which cover pulsed, fast changing, current waveforms. This standard covers the immunity to conducted, differential mode disturbances and signaling in the frequency range from 2 kHz to 150 kHz. IEC 6:2020 is applicable to the immunity requirements of electrical and electronic equipment to radiated electromagnetic energy. In this paper it is shown that the current frequency domain tests are not sufficient to determine the equipment's immunity, because of for instance non-linear effects, including saturation, digital sampling error effects and other non linear time invariant (LTI) effects.ĪB - Testing of electrical and electronic equipment is generally performed using frequency domain tests like the IEC 6. This part of IEC 61000 relates to the immunity requirements and test methods for electrical and electronic equipment subjected to static electricity discharges, from operators directly, and from. However, applications or environments where ESD strikes are expected to have stronger voltages or may occur more frequently require higher contact-voltage and air-gap voltage ratings (Table 2). For example cases are described where static energy meters can give misreadings when loaded with pulsed currents. For most applications, level 4 IEC ESD protection (8kV contact/15kV air gap) is sufficient. This standard covers the immunity to conducted, differential mode disturbances and signaling in the frequency range from 2 kHz to 150 kHz. N2 - Testing of electrical and electronic equipment is generally performed using frequency domain tests like the IEC 6. T2 - European Conference on Electromagnetic Compatibility - EMC Europe 2019 Whereas in the application notes I have read, it shows the 6 dB attenuator in circuit. T1 - Why Frequency Domain Tests Like IEC 6 Are Not Valid If you look at figure 8c in 6 it does not show the 6 dB attenuator in the setup for level setting at the EUT port of coupling/decoupling devices.
