Cost effective uses of close field probing


Cost effective close field probing

This module is designed to help people understand Close-field EMC probing (often called near field probing). This is a useful qualitative method to quickly identify emissions problems.  It can quickly reveal weak points for immunity, when used with transient and/or radio-frequency (RF) generators and it can help design PCBs, shielding and much else.
