Current Probe for Emissions Measurement

The CLCE-452 RF Current Probe is part of Com-Power’s extensive line of radio frequency conducted emission/ immunity test equipment and calibration accessories. The CLCE-452 was designed to accommodate thick cable bundles(s), up to two inches in diameter. It is suitable for compliance level conducted emissions/ disturbance current measurements, such as those required by CISPR 22, CISPR 32, RTCA DO-160 and MILSTD-461 standards, to name just a few. The CLCE-452 incorporates a split-core ferrite into its rugged, circular enclosure. The probe enclosure is hinged, allowing the probe to be opened on one side in order to easily place the wire, cable(s) or cable bundle(s) to be tested into the probe window. This makes the CLCE-452 much more convenient to use than other non-split core probes.
