Radiated Emissions System

Emissions testing involves measuring the amount of RF energy being given off by a EUT. Radiated Emissions tests use a tuned antenna to measure the energy that is being radiated at a given distance. When using a calibrated antenna, the antenna gain factor is included in the measurement to allow the electric field strength to be measured in dBµV/m (decibel micro-volts per metre), or the magnetic field strength in dBµA/m (decibel micro-amps per metre).

The EMC standard will dictate the frequency range to be assessed and the relevant test parameters, such as resolution bandwidth, measurement time etc.

Equipment

Equipment shall be selected by EMC Hire engineers based on the customer needs, therefore please provide as much information as possible (e.g. applicable standard, test limit etc) when enquiring.

The system consists of antennas appropriate to the frequency range, a test receiver, pre-amp (if needed), antenna stand and cables.

An automatic mast and turntable can be provided for fully-automated systems when applying the EMC Directive.

A laptop containing DARE RadiMation test software is included in the system, which will be preloaded with the appropriate test configurations including transducer factors. A software operating procedure is also included to guide you through using the software.

Test Support

EMC Hire can provide an Engineer to set up the system at your location if required, or can offer remote assistance via Teamviewer or Teams.

Standards that can be provided include:

  • CISPR 16-2-3
  • Mil Std 461 – RE101 / RE102
  • Def Stan 59-411 – DRE01 / DRE02
