EMI / EMC Testing Services in Colorado

10 Meter EMI Chamber

  • CBTL Certified Testing - NTS is one of the few CB Testing Laboratories (CBTLs) for electromagnetic compatibility in the United States. We can accommodate CB Scheme EMC testing on medical products for world-wide compliance. Our scope includes 2nd, 3rd, and 4th editions of IEC 60601-1-2.
  • Commercial EMC Testing - NTS has the ability to test a wide range of commercial products, from battery-powered, handheld meters to electrosurgical generators. Full compliance emissions and immunity testing is performed under one roof.
  • Medical EMC Testing - NTS tests electronic devices used in a hospital environment or other medical applications including life support equipment, generators, and x-ray equipment as well as smaller devices such as pulse oximeters.
  • Military and Aerospace EMC Testing - NTS Longmont has provided EMC testing services on a number of programs, including the International Space Station and the C-17 Globemaster. MIL-STD testing, trouble-shooting and mitigation and design has been performed on actuators, CCUs, Launch, IR and UV cameras, and more.
  • Prescan & Mitigation - NTS provides engineering-level EMC immunity and emission testing for all tests that will be required for full compliance. Pre-scans are abbreviated tests which aim to identify potential problem areas earlier in the design cycle.
  • Pre-scan Emissions Testing - Enables clients to determine whether or not a compliance problem exists long before it can impact time to market. Pre-scan services have found that we offer an excellent environment for them to trouble-shooting EMC issues.
  • Two fully accredited 10-meter chambers - NTS Longmont boasts two fully accredited 10-meter chambers for our emissions testing, giving clients the advantage of more reliable data while saving them time and money.
