Abstract :
The dispersion of the measurement of electromagnetic disturbance above 1 GHz is mainly affected by site imperfections (expressed by SVSWR). To evaluate the uncertainty in electromagnetic disturbance measurements at 1-18 GHz, we measured SVSWR and the field strength at 9 measurement site. From our result, the measured field strength at each measurement site was observed in the range of 2σ that derived from measured SVSWR, and we confirmed the relationship between SVSWR and the measured field strength. Using the relationship, we can determine the measurement uncertainty of measured field strength at test site.
