Experimental Investigation on Electromagnetic Radiation Effects to an Electronic System Through EMP Source
The radiation effect experiment to a complicated electronic system by using of GW ultra-wide band (UWB) radiation source has been carried out. In cases of opening or closing the door of device under test (DUT ), the responses of test points on combination No.04 and No.08 of DUT have been measured. The response characteristics of test points on combination No.02 have been tested at different orientations of antenna of EUT. And spectrum analysis has been performed for response waveforms. The results have shown that the response voltage on internal circuits of EUT may reach about 1.6kV at condition of opening door of DUT when radiated by UWB source with 2.0 ×10 4 V/m of field strength (rise time is 0.3ns and pulse width is 3~4ns). The maximum response voltage on combination No.02 is about 1.6kV under condition of optimum coupling of antenna. In this case, some of the electronic components which are sensitive to electromagnetic field may be damaged.
