Abstract (in Japanese) (See Japanese page) 
(in English) In order to investigate the effectiveness of an SMA receptacle as wideband measurement electrode for human electrostatic discharges (ESDs), we derived the transfer impedance of a 50-ohm SMA receptacle, and measured its frequency characteristics from 300 kHz to 20 GHz. With a 12-GHz digital oscilloscope, measurement of discharge currents through a hand-held metal bar from a charged human was made, and thereby the injected currents on the SMA receptacle were reconstructed from the measured transfer impedance. As a result, we found that at a charge voltage of 1500 V the reconstructed current waveform agrees well with the observed voltage waveform divided by 50 ohm while at a charge voltage of 300 V, the reconstructed current oscillates at a frequency of about 7 GHz, and also has faster rise time and larger peak than the observed voltage.
