Equipment Overview
Samples and Resrictions: The electromagnetic shielding room is used to isolate the electromagnetic environment indoors and outdoors to ensure the normal operation of indoor electronic and electrical equipment. Mainly used for conducted emission test, conducted immunity test, EMI discontinuous interference test, etc.
Application: Electrical appliances and electronic devices, including in-car electronic systems, generate a certain amount of electromagnetic waves at work that may interfere with surrounding equipment or be received by specialized equipment.
The electromagnetic shielding room is used to isolate the
electromagnetic environment indoors and outdoors, which can prevent
external electromagnetic interference from entering the room to
affect the test, and can limit the electromagnetic leakage of
indoor high-power high-frequency equipment to prevent the influence
to people and equipment around. It is the ideal venue for EMC
testing.
Test Principle: Electromagnetic shielding room is mainly used for automotive
electronic conduction emission (CE) test, transient conducted
immunity test, bulk current injection method (BCI) test, stripline
method test, etc.
