• For the coupling during immunity tests according to IEC/EN 61000-4-6
• Frequency range 10 kHz - 1 GHz
• Suitable for cables up to 35 mm, for thinner cables up to 20 mm: use CDN EMCL-20
• EM-coupling clamps for immunity tests on cables up to 35 mm diameter
• Low insertion loss: less than 15 W amplifier power is required to achieve the highest test level of 10 V
• Supplied as standard with calibration set and individual calibration data

EM coupling clamps are always used when the use of coupling / decoupling networks (CDN) does not seem suitable or appropriate. This applies, for example, to unshielded cables consisting of a large number of individual conductors. With the electromagnetic coupling path, both capacitive and inductive coupling into the cable connected to the test object is achieved.

The EM coupling clamp has a directivity of ≥ 10 dB above 10 MHz, so that a defined impedance between the asymmetrical connection point of the auxiliary / additional equipment and the reference ground plane is no longer required. Above 10 MHz, the behavior of the EM coupling link is therefore similar to that of coupling/ decoupling networks.

The calibration set and individual calibration data are included as standard, along with:

• 2 mounting brackets incl. 50/150 Ohm transition
• 1 piece BNC termination, 50 Ohm, 1 W
• 1 adapter with banana plugs for calibration of the network analyzer, length 34 mm
• 1 piece brass rod 4 mm with banana plugs for setting the test level, length 672 mm
• N male to BNC female
