CLEM-6146 - Injection device for conducted immunity tests

150 kHz to 1 GHz

Electromagnetic Clamp

▸ CLEM-6146 electromagnetic clamp (EM clamp) for IEC/EN 61000-4-6 conducted immunity testing — a clamp-type RF injection device covering 150 kHz to 230 MHz, with an extended frequency range of 10 kHz to 1 GHz for product-specific conducted susceptibility tests.
▸ Combined capacitive and inductive coupling for highly efficient RF injection — the EM clamp couples disturbance energy onto the EUT cable through both electric and magnetic fields, delivering required test levels with less amplifier power than current-injection clamps.
▸ Directs RF energy toward the Equipment Under Test (EUT) — the clamp couples RF onto the EUT-to-Auxiliary-Equipment (AE) cable while decoupling the AE path, concentrating the conducted disturbance where it is needed for accurate IEC 61000-4-6 immunity evaluation.
▸ Hinged split-core ferrite design for fast, repeatable cable setup — the top half of the enclosure opens so the cable under test can be laid in place without disconnecting connectors, making it ideal for production and lab conducted immunity testing.
▸ Quarter-turn locking mechanism for consistent ferrite compression — two front knobs rotate a quarter turn to clamp the upper and lower ferrite halves firmly around the cable, ensuring stable, repeatable coupling between test runs.
▸ Preferred alternative to CDNs for multi-conductor and non-standard cables — the EM clamp is used when a suitable coupling/decoupling network is unavailable, supporting conducted immunity testing of complex signal, control, and data cables.
▸ Ideal for industrial, automotive, medical, and ITE conducted immunity programs — helps manufacturers verify equipment resistance to radio-frequency disturbances induced on interconnecting cables per IEC/EN 61000-4-6 and derived product standards.
▸ Integrates with Com-Power conducted immunity test systems and three-year warranty — pairs with ACS-series RF power amplifiers and the SPA-900TG series spectrum analyzer for a complete, standards-compliant EMC immunity test setup.

How it works: The cable between the EUT port under test and its Auxiliary Equipment (AE) is laid into the open EM clamp. The clamp couples RF disturbance energy onto the cable and decouples the AE path, directing the energy toward the EUT for IEC/EN 61000-4-6 conducted immunity evaluation.
Typical setup: Signal generator → ACS-series RF power amplifier → CLEM-6146 EM clamp → EUT cable, with a spectrum analyzer / EMI receiver used for level setting and verification.
