In this paper, we investigate the use of frequency modulated signals for immunity testing of integrated circuits. The aim is to predict their electromagnetic susceptibility based on realistic noise signals. These signals reflect the complexity and diversity of real electromagnetic disturbances. The approach uses both narrowband and broadband modulation signals during testing as an efficient alternative to the conventional approach using continuous wave signals. The advantages of using the presented interference signals compared to the conventional ones are analyzed and the influence on electromagnetic immunity is shown in comparison using the direct power injection method on an automotive smart power high-side switch.
