Summary :

An automated measurement system has been developed for measuring a magnetic-field strength inside and outside a motor vehicle exposed to an electromagnetic-field (EM-field). This measurement system consists of an EM-field generator unit, a magnetic-field probe, a data transmission unit with a fiber optic link, a graphic computer and its peripherals. The system is capable of measuring an EM-field strength of 4085 dBµA/m within a frequency range of 20200 MHz, with a certainty of 0.5 dB. The time required for the measurement is approximately three minutes per axis of X, Y or Z at one measuring point when the measurement is repeated five times per specific frequency at 2 MHz intervals for a frequency range of 20200 MHz. This measuring time is one-twentieth as long as that required by conventional unautomated measurement sets.
