Immunity scanning methods can be used to locate sensitive areas on PCBs and ICs. For the analysis of emissions near field scanning is used to determine the local field strength. Both methods have many similarities and differences. For both methods it is difficult to correlate between board level scanning and system level test results as neither method shows the coupling path directly. The paper shows the implementation of an immunity scanning system and analyzes the advantages and limitations of immunity near field scanning.
