Principle


EMI shielding, of high importance in the electronics industry, measures the effectiveness of a material to protect signals from being disrupted by external electromagnetic signals, as well as preventing generated signals from interfering with surrounding components.


Capabilities


20KHz - 15.GHz

  • ASTM D4935
  • Repeated sweeps are made across the frequency range and averaged for both the shield and blank specimens
  • 6" square sample or larger (minimum 4 required)
  • Testing temperatures (lab ambient)
