Radio frequency susceptibility testing is usually conducted inside an unoccupied shielded enclosure. The purpose of the test is to determine if the equipment under test (EUT) malfunctions due to exposure to these electromagnetic fields. Prior-art test methods used only a spectrum analyzer in conjunction with a signal generator and power amplifier to generate the proper fields. This method requires the test procedure to be stopped frequently to determine if an error has occurred. When an error is detected, portions of the test must be repeated to identify the exact frequency and susceptibility level. A system that continuously monitors the error status of the EUT while performing radio frequency susceptibility (RFS) evaluations without interfering with the test fields is accomplished using this remote detection system.
