Conducted Emissions System

Emissions testing involves measuring the amount of RF energy emanating from an EUT. Conducted Emissions tests measure the amount of energy being given off by a cable or harness.

Two methods can be used to measure the conducted emissions:

1. A current probe is positioned around the cable under test. The RF current flowing in the cable generates a changing magnetic field around the cable.  The current probe acts in the same way as the secondary winding of a transformer, with the harness under test being the primary, measuring the generated magnetic field in dBµA.

2. The power cables of an EUT can be connected to a LISN, with the conducted emissions measured directly from the RF output on the LISN in dBµV.

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 customers needs, therefore please provide as much information as possible (e.g. applicable standard, test limit etc) when enquiring.

The system shall consist of equipment appropriate to the test method and frequency ranges of interest.

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.
