Conducted Immunity System
Conducted Immunity testing involves injecting RF voltages or currents onto the cables to an Equipment Under Test (EUT) to confirm that the RF will not cause degradation of performance or deviation from the specifications of the EUT. The test simulates the proximity of the EUT and its connected cables to radio transmitters operating at low frequencies. Injecting low-level RF signals and high-frequency current into wires and cable bundles is a common requirement in the EMC test world.
Standards that can be provided include:
- EN 61000-4-6
- ISO 11452-4 / SAE J1113-4 / Ford / JLR / DC / GM and other OEMs
- MIL-STD-461
- Def Stan 59-411
- Def Stan 61-5 – DIT03.A
Equipment and Support
Equipment
Equipment shall be selected by EMC Hire engineers based on the customer's needs, therefore please provide as much information as possible (e.g. applicable standard, test level, size of EUT cables, etc.) when enquiring.
The injection device can be a CDN, EM Clamp, BCI probe or Coupling Transformer, depending on the standard.
A monitoring probe can be used, depending on the standard applied, to record the amount of current flowing in the cable under test.
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.
Calibration
Due to large variations of circuit impedances and resonances in cables, a calibration is performed to establish the forward power into the injection device required to develop the required test level. This is stored in the software for playback onto the EUT.
If required, the conducted immunity calibration can be performed by EMC Hire prior to the hire.
