The AB-EM electromagnetic clamp complies with the national standard IEC 61000-4-6 and is a specialized product for testing the immunity of equipment to radio-frequency field-induced conducted disturbances.injecting disturbance signals into the cable assemblies in the slots so that the Equipment Under Test (EUT) is subjected to the levels specified in the national standard.

For precise measurements, the electromagnetic clamp is also equipped with an auxiliary absorption clamp and calibration pieces.

Features

See Tables 1 and 2 for the coupling coefficient and attenuation characteristic curves; the difference is 9.5 dB ± 1.5 dB.

Maximum input power: 100 W (5 minutes);

Injection frequency: 150 kHz to 230 MHz;

At frequencies greater than 10 MHz, the coupling/decoupling directivity is greater than 10 dB

Measurable cable diameter: <Φ18 mm
