AD-CISPR16-1-4 Overview
The AD-CISPR16-1-4 can be used for both, coaxial cables and unshielded cable bundles, to suppress unwanted common mode currents (also called braid currents). Since these unwanted common mode currents are very often a reason for poor repeatability of measurements, the new CISPR 16-1-4 standard recommends the use of absorbing clamps. The ferrite clamp meets the requirements from 30 - 200 MHz and is usable up to 1 GHz.
Construction of the clamp consists of many precision cut ferrite half-toroids, embedded in a grey plastic housing. The unique floating toroid bearing ensures a perfect fit of the ferrite surfaces. Two quick-locks at the long side allow opening and closing of the clamp within seconds. Cable bundles or coaxial cables with a maximum diameter of 26 mm are accepted by the clamp without disassembling connectors or interrupting any circuitry. The combination of short length and large cable hole diameter offers a broad variety of applications for the AD-CISPR16-1-4. Each common mode absorption device comes with an individually measured calibration certificate.
Calibration:
The AD-CISPR16-1-4 can be calibrated with the optionally available "AD-CISPR16-1-4-CAL" calibration set as described in CISPR 16-1-4.
