You can isolate and evaluate emission hot spots with the Agilent 84105EM EMC Design Development system, that will include an E7401A EMC analyzer and an 11945A close field probe set. The probes are calibrated in magnetic field strength units so that the emissions displayed on the EMC analyzer are in dBuA/meter. By knowing the field strength, you can derive the current at a specific frequency. Since the probes measure magnetic field strength versus electric field strength, the repeatability is good. You can use the probes to locate RF leaks in shielding and cabinets.
