EN 61000-4-6 (2014-08) Ed. 4.0 Features: · EM clamp for immunity testing of cables with up to 20 mm diameter · High coupling factor: less than 15 watts amplifier output power is required to obtaina test level of 10 V · Calibration unit and calibration data are supplied with each instrument Description: The preferred coupling and decoupling devices are the CDNs, for reasons of testreproducibility and protection of the AE. However, if they are not suitable or ailable,clamp injection should be used. Often, clamp injection needs to be applied to multi-pair balanced cables because suitableCDNs might not be ailable. The EM clamp establishes both capacitive and inductive coupling to the cable connectedto the EUT. The EM clamp (in contrast to the conventional current injection clamp) has a directivity ≥10 dB, above 10 MHz, so that a defined impedance between the common-mode point ofthe AE and the ground reference plane is no longer required. Above 10 MHz, thebehiour of the EM clamp is similar to that of a CDN. CDN-EMCL (EMCL-20), EM clamp acc.
