Analysis upon the effect of the immunity of electronic devices by the emitted digital modulated signals

Using a variety of digital modulation schemes for mobile communication technology, and despite the fact that these are serviced, the radiated immunity test based on IEC 61000-4-3 only has been performed using AM signal. In this study, we had performed the radiated immunity test using the digital modulation signals and an AM signal, and had investigated the impact of digitally modulated signals. The results show that the devices were influenced by digital modulation signal or PM signal more than by AM signal. This result shows that we need to investigate the depth research on radiated immunity testing for the environment of modern communication technology.
