Abstract

In this paper, a generic susceptibility model of a personal computer (PC) was derived using generic coupling characteristics of cables, enclosure with apertures, and a circuit board. Using experimental upset data for digital semiconductor components, electric field intensities were calculated for an unshielded PC board and a typical PC. The obtained results show the envelope of an electric field intensity to which a PC is susceptible with the minimum and maximum margins. A typical PC is most susceptible at frequency ranges 3-500 MHz and 700-1500 MHz, with an upset threshold of 250 V/m for a typical PC and 55 V/m for an unshielded PC board.
