In order to study the correlation of the electromagnetic radiation susceptibility tests in a reverberation chamber and an OATS, the physical model of a reverberation chamber and an OATS is established separately by using the electromagnetic simulation software FEKO. Six frequencies (200,0, 500,0, 800,0MHz) are chosen in the common work frequency band (range of 170MHz to 1GHz) of the reverberation chamber and the OATS. At each frequency the induced currents in the small electrical monopole antennas in the reverberation chamber and the OATS are calculated. The electric field strength in the relevant position is also calculated. The data are statistically analyzed. It is concluded that the correlation of the normalized induced currents in the monopoles is very good.
