EM Coupling Clamps

(Showing 12 of 15)

The integrity of both communication and electrical lines within products of all shapes and sizes is important to address early in design stages. EM coupling clamps are used to monitor electrical and magnetic characteristics radiated from electrical/communication wires. Additionally, you can generate electrical and magnetic fields using a clamp to inject distrubances onto the lines and evaluate their response. EM clamps are used to meet CISPR, IEC and other compliance standards to evaluate radio frequency disturbances on and around power or data lines.
