Description:

Interference sources are electromagnetic fields generated by RF transmitters within the frequency range of 9kHz to 230MHz. These electromagnetic fields affect the power lines, communication lines, interface cables, and other connecting lines of electrical and electronic equipment. The length of these connecting wires may be comparable to several wavelengths of the interfering frequency, thus, causing these wires to become passive antennas that receive external electromagnetic fields. The interference can then be coupled into the devices through conduction (ultimately causing RF voltage and current-induced near-field electromagnetic interference within the devices) leading to disturbances and impacting their normal operation. The aforementioned interference can be categorized as cable shielding and signal interference.

Scope: The testing frequency ranges from 150kHz to 230MHz, with a maximum test level of 20V.

Scope of Application:

Electronics and electrical products.
