It details measurement techniques (voltage dividers, step-down transformers, etc.), the impact of environmental and connection factors on accuracy, and why traceable calibration (e.g. to NIST / A2LA) is a must to ensure consistent, reliable results.

The comprehensive turnkey EMC test chamber solutions we offer:

  • Anechoic chambers
  • Anechoic chamber upgrades
  • Reverberation chambers
