Radiated immunity has started to become very common and is nearly impossible to set up in-house without great expense and trained test operators. Often it involves endless cycles back and forth between adding random fixes in-house and then running back to the compliance test lab. This delay can negatively affect product introductions. This presentation will describe a simple method for troubleshooting and mitigating immunity issues right on the lab bench. Often, the root cause is due to interconnecting cables acting as receive antennas and coupling RF energy into sensitive circuits. Two interesting case studies will also be described.
