Our EMC Testing Capabilities

Customers can choose from convenient 10, 5, or 3-meter anechoic and semi-anechoic laboratories throughout the U.S. We can accommodate small signaling equipment to whole locomotives. Our capabilities enable us to test to the highest levels required by the EN50121 series of standards.

Where products are too physically large to be assessed in a test chamber, we can test in situ.Our mobile team with specialized field equipment can test at your location – indoors or outdoors – throughout North America.
