When running a test, this may be done if the EUT is not susceptible, but the auxiliary equipment is. To mitigate this, a technician or customer may wrap cables in foil, apply ferrite beads, or rearrange the auxiliary equipment setup to prevent the susceptibility from continuing. This precaution is sometimes done as a mitigation step to determine if cables are culprits for excess radiated emissions. It is important to note that if foil is required as a solution to mitigate immunity or emissions, equivalent shielding will be necessary for the EUT’s actual installation.
