A screen connection and its measured EMC behaviour
- EMC cable glandThis term
The entry makes a specified screen connection to the enclosure. Confirm the cable preparation, contact geometry and tested assembly.
- EMC
Compatibility considers emissions and immunity in the operating environment. A single shield component does not establish system EMC.
- EMI
A disturbance can couple into another circuit and affect its operation. Identify the source, coupling route and affected equipment.
- Screening attenuation
The result describes attenuation in a defined screening test. Compare frequency range, fixture and specimen mounting.
- Shielding effectiveness
Compare the field or coupling with and without the defined shield. Gaps, seams and entry interfaces belong to that assessment.
- Transfer impedance
Screen current is related to the induced voltage on the other side. State frequency, units and any length normalization.
A cable screen needs an appropriate path through the entry. Interference, compatibility and the different screening measurements describe the resulting system from different perspectives.
Conceptual EMC paths with no attenuation curve or rating. Test fixture, frequency, specimen length and complete mounting arrangement must accompany performance values.
