Radiated Emissions Testing

Notice: This information is a brief, elementary overview for someone looking to perform precompliance EFT testing in effort to pass EN/IEC 61000-4-4. For step by step test procedures you will need to purchase the test standard for detailed instruction.

Radiated Emissions - EMC Testing

Replicating an EMC test lab is a challenge, however, most of our customers will setup an RF tent to isolate noise while testing their product. After setting up a directional antenna and connecting to a spectrum analyzer, they are off and rolling. Test standards can provide specifics regarding spacing, insulation, placement , etc... We have found that in most cases, these aren't detrimental pieces to getting reliable emissions measurements. Most EMI software will have the test levels pre-programmed for common radiated emissions test standards.


Radiated Emissions Test Setup

RF Radiated Emissions Test Setup - EMC

Getting Started

  • Determine Frequency Range
  • Antenna Requirements (Dist and Polarity)
  • DUT Rotation

Near field measurements are done to pinpoint and identify sources of radiation

Radiated Emissions - Field Testing

In the field radiated emissions testing is done to evaluate an environment with many known radiators present or evaluating a specific installation.

Radiated Emissions Testing In Situ


Field Testing Applications

  • In-situ EMC
  • Site Validation (Cell towers, Railway, etc)
  • RF Interference Identification
  • Environmental Surveying
