Electromagnetic Compatibility

EMI issues are often encountered during compliance testing when design corrections are the most costly. Time to sprinkle the ferrite beads and filter caps and add on some shielding! Often, these weaknesses could have been detected early in the design process.

EMI Testing

Clevenstine Engineering can provide assistance with the development of your designs to help ensure your product will be free of EMI issues.

Filters - Filters are often added with good intent, but will those filter components perform as expected over the range of EMI frequencies?

PCB layout - Location of components and the routing of the traces can make or break the EMC performance of your product.

Ground Planes - Ground? Chassis? Circuit common? And when is a ground plane a good idea or an unnecessary expense?

Shielding - Now that your shield is in place, how do you terminate the shield? ...and to what? ...and in how many places? If you simply terminate the drain wire on a chassis screw close by, you may not get the effects you were hoping for!

Twisted pair and Coax - When do you use one versus the other?

Internal Cabinet Arrangement - Attention to the positioning of the internal components and their interconnections will ensure your equipment performs at its peak.

Cabinet Enclosure - Get it all wrapped up to keep the noise out!

Compliance Testing - Help you sort through what to expect when you go to the Testing Facility:

  • Conducted Emissions
  • Conducted Susceptibility
  • Radiated Emissions
  • Radiated Susceptibility
