There is no doubt that the use of a current probe can effectively illuminate problems with an EUT. But the method can really only be used effectively up to about 200MHz or so and (heres the kicker) is about 6db harsher on the EUT than the Radiated Immunity test. In other words, you may cause a failure with the probe that the cannot be repested in the RI test. Thank you Charles Grasso (Capn Hook)
