Product Description

Absorbing Clamp CLA-050

It is specifically designed according to CISPR 16-1-3. It is used to measure disturbance power on power input lines as well and other auxiliary I/O lines. The measurement of disturbance power is a method for determination of radiated disturbance, & an alternative to the measure the disturbance field strength on an Open Area Test Site (OATS) or Semi-Anechoic Chamber (SAC).  The use of an absorbing clamp of disturbance power measurements is required for different types of devices per CISPR 13 [EN 55013], CISPR 32 [EN 55032] & CISPR 14 [EN 55014]. Absorbing Clamp can also be used to measure screening attenuation of RF coaxial cables.
