Despite of widespread use of new digital wireless communications, the radiated immunity test based on IEC 61000-4-3 only has been performed with using amplitude modulation (AM) signal. In this study, we have analyzed the radiated immunity test method that is going on recent standardization activity to investigate close proximity fields from radio frequency (RF) wireless communications and have investigated the impact of digitally modulated signals. The results show that the devices were influenced much more by digital modulation signal than by AM or pulse modulation (PM) signal. Also it shows that we need to investigate the depth research on radiated immunity testing for the environment of modern communication technology.
