Sulis staff have been fixing EMC test failures and making products comply with the EMC directive since it was introduced and can help you make design changes required to comply with EMC standards.

We own a number of pieces of equipment including spectrum analyser, LISN, ESD gun and surge/burst generator, which can be brought to your offices to perform tests, diagnose problems and recommend solutions.

Fixes we have implemented include:

  • Reducing mains Conducted Emissions by up to 40dB through design and implementation of suitable single, dual or three stage filters on power lines.
  • Reducing Radiated Emissions by 30dB through improvements to shielding and enclosure construction, better matching of clock terminations and addition of ferrites where this is the most pragmatic solution.
  • Improving Radiated Immunity resilience by a factor of 3 – generally through improvements to bonding, shielding and cable terminations.
