  In this study, we established a method of observing the waveform of the test burst EFT / B. The probe used in ordinary oscilloscope waveform ringing occurs in the burst. So we fabricated this probe. As a result, we were able to suppress this ringing. A burst waveform was reproduced using a circuit simulator. This is the first study to connect a capacitor in parallel with the load resistance as protection against EMC and was further verified in the simulations. The analysis results increase as the capacitance of the capacitor increases. From this the burst waveform is considered to be reduced. Analysis of the results of this simulation is consistent with the use of a capacitance of 2.2μF.
